Nine-Channel Polychromator For Observation Of Time-Dependent Spectral Line Profiles

Description: The instrument (polychromator) described observes time-dependent spectral-line profiles by simultaneous measurement at nine different wavelengths of light intensity as a function of time. A cylindrical lens magnifies the dispersion of a Jarrell-Ash Model S2000 Ebert Monochromator and forms an image on a light-pipe solder. Light pipes transfer light from various sections of the image--i.e., different wavelengths--to photomultiplier tubes, and the responses are displayed on oscilloscopes. The ins… more

Influence of Different Y Chromosomes on Secondary Nondisjunction in D. Melanogaster

Description: Females heterozygous for a wildtype X chromosome from a Samarkand stock and an chromosome of the composition [formula] were tested for the frequency of X-chromosomal non-disjunction and segregation of the X's when Y chromosomes of different types were present in the females. The Y chromosomes used were 1) a normal unmarked Y, 2) [formula], 3) [formula] and 4) [formula] (a chromosome which arose in one of our experiments and has not yet been analyzed). Since this was only a preliminary test no a… more

The Tides: A Dynamic Explanation Based Upon Fundamental Physical Concepts

Description: A model is proposed to directly relate observed tidal action with orbital movements of the moon and the earth. The basic model consists of a unit mass acting as a free point on the rotating earth's surface and being carried into a field gradient. The field is such as to cause the free point to "fall" along the surface, gain a velocity with respect to the earth's surface, and thus produce a tidal interaction at coastal barriers. Gyroscopic and resonant oscillatory current effects are not treated. more

Decay-Energy Systematics Of The Heavy Elements

Description: Figures 1 and 2 summarize total decay energies for the four radioactive series. The alpha-decay energy obtained by measuring the energy of the alpha particle leading to the ground state includes the energy of the recoil nucleus. The curve shown in figure 3 defines in broad outline the conditions and regions of alpha instability. A great deal more is to be learned from a more detailed examination of the region where alpha radioactivity is prominent. Of great value to the experimentalist is that … more

Energy Response And Physical Properties Of NTA* Personnel Neutron Dosimeter Nuclear Track Film

Description: This paper reports the chemical and physical properties of the NTA film packet. It correlates with these properties the response of this packet to neutrons of various energies. In this correlation the concept of the track unit is introduced as a basic unit for reporting film-packet response.

Possible Manifestations Of A Pion-Pion Interaction

Description: The pion-pion interaction is of great theoretical importance and must be understood before the other and more familiar interactions can be systematically analyzed. Therefore, various experiments to verify the existence of a P resonance in the w w system are proposed.

Comparative Costs Of Sea Disposal And Land Burial For The Radioactive Wastes Of The Lawrence Radiation Laboratory

Description: This report is a comparative cost study of radioactive waste disposal for the Lawrence Radiation Laboratory (UCRL). In particular, it compares the costs of sea disposal in depths of 1000 fathoms and of 2000 fathoms off the California coast with land burial of the wastes at the Hanford Atomic Products Operation (HAPO), Richland, Washington, at the National Reactor Testing Station (NRTS), Idaho Falls, Idaho, or at the Nevada Test Site (NTS), Nevada. In the comparison, the cost of utilizing a comm… more

The Homopolar Device

Description: This paper is intended as a preliminary report on the Homopolar configuration (axial magnetic field with radial electric field), which is the rotating configuration most thoroughly studied thus far. The analysis presented in this paper applies principally to the "ideal" Homopolar, that is, the configuration free from electrode-sheath drops and other disturbing but remediable phenomena. Design considerations for various interesting plasma appliances are derived and documented with preliminary ex… more

Radiation Hazards In Space Flight

Description: During the past five years, potentialities of space travel have greatly increased and new knowledge has become available regarding the nature of cosmic radiation. In the present article the knowledge pertinent to dose evaluation is reviewed for conditions of flight in space in the vicinity of the earth but away from the influence of its atmosphere or magnetic field. Certain properties of the heavy nuclei are also discussed as well as some of the available information on their actual biological … more

Evidence For The Angular Distribution of Negative Pions Produced in n-n Collisions

Description: The angular distribution of charged pions from 100 = 30 Mev neutron bombardment of C12 and Be9 has been measured. These data may be used to infer, by subtraction, the identity, within limits, of the [formula] and [formula] angular distributions.

Total Neutron Yield From Targets Bombarded by Deuterons and Protons

Description: The total number of neutrons emitted from various targets bombarded by high energy deuterons and protons was measured by using a solution of MnSO<sub>4 to thermalize and capture the neutrons. The methods of monitoring the number of particles striking the target and of calibrating the neutron detecxting apparatus are discussed in detail. Deuterons of energies to 230 Mev and protons of energies to 345 Mev were used. Targets ranging from lithium to uranium were used and were backed by secondary ta… more

The Characteristics of Bismuth Fission Induced by 340 Mev Protons

Description: Bismuth metal was irradiated with 340 Mev protons in the circulating beam of the 184-inch Berkeley cyclotron. Nuclides formed as fission products during the course of the bombardment were separated and studied through the use of radiochemical techniques.

Recent Total Neutron Yield Measurements

Description: The report summarizes results obtained since September, 1951, by total neutron yield experiments using 190 Mev deuterons and the MnSo4 tank method (UCRL-1375 and UCRL-1480). A new method of beam monitoring has resulted in establishing firmly the absolute yield for solid uranium and thorium primary targets backed by a solid uranium secondary. The beam monitoring was done by using a primary target built into a faraday cup. This method circumvents errors caused by recombination in the ionizatio… more

The Chelate Process, IV. Process Flow Involving o-Dichlorobenzene as the Solvent for TTA

Description: Comparative studies of a series of halogenated solvents, as carriers for TTA in the chelate process for plutonium extraction, indicate that ortho-dichlorobenzene most nearly satisfies the requirements that are set forth. A complete process design is presented for use with this solvent, and flow data and equipment capacities are given for dissolver solution and for uranium-free fission product solution as alternate feeds to the process.

Alkyl Phosphoric Acids as Extraction Agents for Uranium

Description: The recent interest in tributyl phosphate as an extracting solvent for uranium indicated that consideration of n-butyl phosphoric acid for this application might be of interest if some way could be devised to overcome the manipulation and miscibility difficulties. It was found that if the material was placed in any one of a number of carrier solvents, it had a remarkably strong extractive effect on uranyl ion out of acid solutions without a salting agent present.

Studies in Beta and Gamma Ray Spectroscopy

Description: The study of artificial radioactive isotopes is at the present time one of the most important topics in nuclear research. It involves the establishment of a detailed term scheme for the disintegration in question. Not only are the energies of the components of the different beta and gamma radiations of interest, but also their intensities. These data give information concerning the probabilities of transitions between the different nuclear energy levels. From them it is possible to draw con… more
