A Programme for Ray Tracing Through a Magnetic Lens System

Description: A ray tracing programme has been written for the IBM 7090 which will trace rays through the following types of region. 1) Free space. 2) Quadrupole with 8, 12, 20 pole aberrations. 3) Bending magnet with 6 and/or 10 pole aberrations. 4) Zero length sextupole (ie. only deflects the ray). subroutines are incorporated which permit the rotation and the displacement of the above elements. In addition, a focusing routine enables the calculation of beam parameters in order to obtain given ray configur… more

High Energy Separated Beam for the 80" Chamber

Description: The angular separation of two particles of different mass obtained by means of a crossed electric and magnet field spectrometer is proportional to the length of the separator and to the electric field but inversely proportional to the cube of the momentum. The availability of the new A.G.S. separators will permit a three fold increase in the length of separator over the existing 3.7 Bec/c beam, while the maximum electric field is expected to be approximately the same. It is, therefore, clear th… more

Theoretical Calculations of Kinetic isotope Effects for Some Nucleophilic Substitutions of Methyl Iodide

Description: Experimental data are available for the kinetic isotope effects of four substitution reactions of methyl iodide. Theoretical calculations for the four reactions have been carried out in order to gain understanding of the causes of the isotope effects and to investigate the conclusions with respect to the transition state which may ben drawn form experimental isotope effect data. Calculations for two of the reactions will be discussed in detail.

Biomedical Reactor Investigations

Description: Biomedical work with reactors falls into four main categories; activation analysis; the use of isotopes produced in the reactor particularly, short lived isotopes; radiobiological investigations using the reactor beams; and approaches to the therapy of neoplasia using neutron radiations from the reactor. The first two, activation analysis and short lived isotopes, are adequately covered by other speakers. With respect to radiobiological research the possibilities are extensive and are limited o… more

The Independence Hypothesis in the Statistical Theory of Nuclear Reactions

Description: From International Congress of Nuclear Physics, Paris, July 1964. The independence of formation and decay of the compound nucleus system in the region of strongly overlapping resonances is investigated within the framework of R-matrix theory. Use is made of recently derived random sign rules based on the statistical distributions of reduced width amplitudes and of resonance energies. The independence law as expressed by the factored form of the partial reaction cross section is shown to be asym… more

Low Temperature Embrittlement of Iron, Iron Alloys and Steels by Neutron Irradiations

Description: The low-temperature embrittlement of iron, iron alloys, and A212-B and modified Hy 80 steels in unirradiated and irradiated conditions was studied using the tension test. A radiation-induced transition temperature (embrittlement) at 125 to 130 K occurs only in irons with carbon content of about 30 ppm or greater. Embrittlement occurs with exposure as low as 2 X 1018 nvt and the embrittling temperature does not increase with exposure. This embrittlement is attributed to a carbon-vacancy defect f… more

The Use of Nuclear and Chromosomal Variables in Determining and Predicting Radiosensitivities

Description: Technical meeting, Use of Induced Mutations in Plant Breeding, FAOUN -- IAEA -- EUCARPIA, Rome, Italy, 5/25-6/1/64. In the two most recent reports, species with greater variation in both chromosome numbers and nuclear volume were irradiated, and it was found that the critical target volume of meristematic cells appeared to be the interphase chromosome rather than the nucleus as a whole. it thus appears that chromosome number is important only as a convenient means by which the average volume o… more

Ferroelectric Hysteresis Bridge

Description: A transistorized version of the Ferroelectric Hysteresis Bridge proposed by Diamant, Drenck, and Pepinski has been built. This instrument performs in the same manner as the one build after the design of the above mentioned authors. The range of compensation is increased in the new device. The description of the basic bridge and ferroelectric properties is well given by the above authors and I won't dwell on it.

Studies on the Kinetic and Radiosensitivity of Meristems

Description: It is manifestly impossible to understand in an adequate fashion the effects of ionizing radiation on higher plants without understanding something of the cell kinetics of plant meristems. Meristems, like most other proliferative tissues, are heterogeneous in cell type, therefore some understanding of tissue ontology and morphology is also essential. To establish a common baseline, a brief outline of the structure of typical meristems will be given and then cell kinetic studies of some irritate… more

The Excited States of He4

Description: From International Congress of Nuclear Physics, Paris, July, 1964. The reaction D(He3,p) He4 was used to investigate excited states in the He nucleus. The decay of states populated by this reaction was studied using two semiconductor particle detectors and two dimensional pulse height analysis to examine coincidences between charged particles involved in the three body breakups of the D+He3 system. Two excited states in He4 were identified in this way, one at an excitation of 19.99 +- 0.02 Mev … more

Final State Interactions in Few Nucleon Systems

Description: The reaction p(D,2p)n has been investigated using 21.1 MeV deuterons. the protons were detected in coincidence by semiconductor particle detectors, and the energy correlations records by an on-line SDS-910 computer system. final state interactions were observed as peaks in the cross-section at energies near the breakup threshold in the intermediate (n+p) systems. A peak was also seen at a higher energy in the intermediate (p+p) system. A similar investigation of the reaction (D(d,Dp)n, where th… more

GRAPE, a Computer Program for Classical Many-Body Problems in Radiation Damage

Description: GRAPE is s series of 7090/7094 programs, FORTRAN and FAP, for solving the classical equations of motion of a large set of particles. The primary purpose is to simulate the motion of atoms in a crystal. Part I setups up the crystal configuration, calculates entries for various tables needed in other parts and saves this information of a binary tape. Part II integrates the classical equations of motion, checks that energy conservation laws have held, and writes information on a binary tape. Part … more

Dipion Mass Spectra in Antiproton-Proton Annihilations at 3-4 Bev/c

Description: Evidence for resonant behavior in the π+π- mass spectrum at 560 Mev was presented at a recent meeting of the American Physical Society. Because a systematic search had been carried out for resonant structure in all available final state of the pp annihilations, it was difficult to evaluate the statistical significance of a signal observed in any particular spectrum. It was therefor decided to perform a control experiment by measuring a new sample of 5000 events and to study only the relevant ma… more
