Analytic Spin Functions of a Single Variable

Description: There has been considerable recent interest in the development of spin representations which are operations upon analytical functions. The familiar Pauli spin matrix representation, has been sufficient for the solutions of most problems involving nonrelativistic electron spin, but it is to be hoped that, for some problems, an "analytic" representation could be found which has greater physical significance. The new representations that have been presented all hae spin functions of two or more va… more

K [infinity] in Uranium - Water Lattices

Description: This report follows experiments on K[infinity], measuring the element for several red sizes, enrichments, and water-to-uranium volume ratios-(1, 2), by making use of the relation k[infinity] = 0M-[2]B-[2] (M-2 = migration area, B = buckling). The purpose of this report is to compare the experimental data for k[infinity] with values calculated from the four-factor formula k[infinity] = [eta][epsilon]pf.

Radioactive Anthracene-C14 and Acridine-C14 from the Neutron Irradiation of Acridine

Description: Anthracene-C14 has been produced by neutron irradiation of the nitrogen homolog, acridine. The recoiling carbon 14 entities produced by the N14(n,p)C14 reaction were also found in acridine molecules, where the nitrogen had not undergone neutron capture during the course of irradiation. The ratio of activity as acridine to the activity as anthracene was about 19/1. Of the total activity produced in the samples, 3.5% was found as acridine, and 0.2% was found as anthracene.

The Mass Spectrum of Lithium Iodide

Description: The mass spectrum of lithium iodide vapor produced from salt heated in an oven in the ion source of an analytical mass spectrometer was investigated as a function of oven temperature. Evidence was obtained for the existence in the vapor of both monomer and dimer. Partial heats of sublimation to monomer and dimer at 0°K were found to be 44.5 ± 7 and 45.0 ± 2 kcal respectively. The heat of dissociation of (LiI)2 into gaseous monomers was found to be 44.0 ± 2.2 kcal. The partial heat of sublimatio… more

Paper for Glasgow Conference on Nuclear Physics: Cosmotron Production of Heavy Mesons

Description: One might expect that the Cosmotron would offer certain advantages over cosmic rays for the study of heavy unstable particles; provided, of course, that it can produce them. In the first place, the conditions under which they are produced could be controlled to a considerably greater extent. In the second place, it might be possible to arrange conditions under which they would be observed more abundantly, an actual beam of heavy mesons being the ideal situation.

Radiation Damage to Water

Description: Water may decompose under radiation to give hydrogen and oxygen gases and small amounts of hydrogen peroxide. The amount of decomposition depends critically on the nature of the radiation, the kind and amount of dissolved materials present, and the temperature. Destruction of dissolved material may proceed to a greater extent than that of the water itself. The basic theory of these effects is briefly outlined. Engineering problems resulting from radiation chemical effects in water are discussed… more

Paper for Glasgow Conference on Nuclear Physics: Cosmotron Results on Pion-Nucleon Interactions

Description: A considerable number of experiments have been performed at the Cosmotron which deal with the interactions between pions and nucleons. Some of these are concerned with the scattering of pions by nucleons, and some with the production of pions in nucleon-nucleon collisions. I will try to give the general results on both pion scattering and pion production, but it will not be possible to describe many experimental details.

Abstract for the Glasgow Meeting - "International Conference on Nuclear Physics": Gamma Transitions and the Shell Model

Description: The study of the interaction of the electromagnetic field with nuclei has proved very fruitful for the elucidation of many details of nuclear structure. The γ-ray transitions observed in either absorption or emission can be divided into three classes, depending on whether the matrix elements of the transition are (1) much larger, (2) approximately equal or (3) much smaller than those expected for single proton transitions which are usually taken as a norm. In class (1) we find (a) the broad tra… more

Effects of Ionizing Radiation on Seeds of Barley

Description: For some time we have been interested in the influence of radiation with different specific ionizations on the relation of the production of genetic changes to survival and seedling injury in irradiated seeds of barley. Our studies have shown that barley seeds subjected to any given dose of thermal neutrons or fast neutrons are much more uniformly affected than seeds treated with any given dose of x-rays or 2 Mev electrons. In addition, it has been demonstrated that when dormant seeds of barley… more

The Relation of Genome Number to Radiosensitivity in Habrobracon

Description: The problem of finding the site of injury from x-radiation is usually resolved to whether the nucleus or the cytoplasm is more radiosensitive. This is not easily determined sines the various cell components are interdependent and therefore cannot be evaluated separately. One approach to this problem is to compare the radiosensitivity of individuals that differ in the number of sets of chromosomes. Thus, by comparing haploids, diploids and polyploids one can determine whether additional genomes … more

Polarographic Determination of Zirconium

Description: In aqeuous solution hydrogen interferes with the discharge of zirconium. Cozzi added methylene blue to effect a separation of potential; however, only a small part of the zirconium participates in the electrode reaction and the wave is poorly defined. Colichman and Ludewig carried out the polarography in anhydrous methanol and thus avoided interference due to hydrogen ions. It has been found that a polarographic determination of zirconium can be carried out in aqueous solution if the zirconium … more

Bacterial Virus: Radiation and Function

Description: One of the materials most extensively studied with the dry state ionizing particle approach described in the preceding papers has been T-1 bacteriophage. It was one of the earliest materials subjected to cyclotron bombardment in the Yale biophysics group (Pollard and Forro, 1951) and a number of workers associated with the group have from time to time returned to it (Pollard and Jane Setlow, 1954). One reason is that investigation of various functional properties of a single material is relativ… more

Relative Energies of Polar and Nonpolar Valence Bond Functions and Molecular Orbital Theory II

Description: In the preceding note, it is shown that one could introduce correction factors into a molecular orbital theory treatment of the ethylene molecule which bring the results into closer agreement with experiment. These correction factors decrease the separation in energy between nonpolar and polar structures and were therefore found to decrease greatly the amount of configurational interaction in ethylene. Moreover, since state T of ethylene is purely nonpolar while state V is completely polar, the… more

Irradiation Effects on 2S Aluminum

Description: As a result of unreported information, it was suspected by some people that a change in dimension was experienced by 2S Aluminum due to a sudden change in neutron flux impinging on it. This was thought to be of the order of 500 microinches per inch in magnitude. Such an effect, if present, could help explain some of the creep phenomena reported lately (i.e. change in creep rate due to cyclotron bombardment.)

Progress Report - Studies on the Propagation of Gamma Rays in Air

Description: Initial rough measurements of the quality of the gamma radiation from Co-60 in air indicated agreement with the theoretical calculations of Spencer and Fano for an infinite water medium. Further experiments were performed, duplicating the conditions assumed in the calculations. Since the spectral region between 100 kev and 1 mev has already been examined by Hayward, it was decided to investigate in detail the region below 100 kev and above 1.0 mev. Total radiation dosage measurements were made … more
