The Reactions of Mixed Crystals of Rare Earth Fluorides With Fluorine Gas

Description: Thesis discussing the reactions of mixed crystals of rare earth fluorides with fluorine gas. The reactions were "studied gravimetrically by determining the weight increases of mixed tetrafluoride samples upon exposure to fluorine at a pressure of 1 atmosphere and a temperature of 250°C...The nature of the phases produced upon fluorination was studied by x-ray diffraction methods."

The Method of Moments in Quantum Mechanics ; The [Pi]-Mesic Disintegration of the Deuteron

Description: The following report contains two reports to summarize a thesis: first, a report describing the classical moment techniques of Tchebycheff, Markov, and Stieltjes that have been applied to the problem of diagonalizing the Hamiltonian operator; and the second report describes an investigation of the higher-order corrections to the mesic disintegration of deuterons that is considered.

Analysis of the Interaction of 300-Mev Neutrons with Xenon

Description: Abstract: And investigation of the interactions between 300-Mev neutrons and xenon was made by means of a cloud chamber in a pulsed magnetic field of 21,700 gauss placed in the neutron beam of the 184-inch Berkeley cyclotron. Eighty-seven negative pion events and 257 other stars were analyzed. In addition an experimental check was made on the energy of the incoming neutrons. Classification, identification, and angular and energy distributions of prongs associated with all events are presented. … more

Alpha-Decay Studies in the Heavy Element Region

Description: Thesis describing a research conducted to extend observations on nuclear energy levels and how they effect the nucleus itself, and an investigation on the gamma rays associated for the even-even isotopes and to obtain additional data for the oddmass neclei in the hope that more regularities will become apparent for that class of nuclides.

Production of Neutral Photopions as a Function of Atomic Weight

Description: Thesis discussing the relative yield of neutral pions from elements in a reaction "as a function of the quantum-limit energy (the maximum energy of the quanta in the bremsstrahlung beam) of the Berkeley synchrotron." Interpretation of the results leads to values for the mean free path for absorption of the neutral pions in nuclear matter.

Relative Yields of Nitrogen-17 Produced by 190-Mev Deuteron Bombardment

Description: "Yields of N¹⁷ relative to that produced in LiF have been measured in the 190-Mev deflected deuteron and the 380-Mev alpha beams of the 184-inch synchrocyclotron. The measurements have been performed in all the light elements from 0 through V, with the exception of Sc and the noble gases. In addition, yields were measured in the separated isotopes of Mg...Comparisons are made with other types of yield studies performed with neutrons and protons, and the areas of agreement are noted."
