Fission prcduct cross sections were measured radiochemically and mass- spectrometrically for gold bombsrded with 112-Mev C/sup 12/ ions. Cross sections for 43 nuclides were measured for elements from nickel to barium. Thirty-six yields are either primary fission product yields (independent yields) or were corrected (with less than 25% correction) so as to represent independent yields. The independent yields were empirically systematized and a yield-mass curve was constructed. The yield-mass curve is compared with the yield-mass curves obtained from the fission of Bi with 22 and 190-Mev deuterons. The yield systematics indicate that the sum of the mass numbers of complementary fission products is 13 plus or minus 1 amu less tban that of the compound nucleus, and the sum of the charges of complemertary fission products is two units less than that of the compound nucleus. It is postulated that 9 plus or minus 1 neutrons and an alpha particle must have been emitted. Evidence is presented that at least three and possibly more of the neutrons are emitted prior to fission. The most probable charge of the fission products as a function of mass number was determined empirically. It is shown that from mass number 80 to mass number …

The reactions pi /sup -/ + p yields p + p + n and pi /sup -/ + p yields p + d were investigated. The calculations are based on thirdorder perturbation theory with pseudoscalar coupling between nucleons and pions and with a phenomenological treatment of the nucleon-nucleon interaction in the final state. The final-state interactions of the antinucleon are neglected. Cross sections are given in graphical form for the reactions and for trsnsitions between eigenstates of isotopic spin. The final-state nucleon-nucleon interaction is shown to have a lnrge effect on the cross sections. The cross section for the reaction pi /sup -/ + p yields p + d is found to be relatively large. At an energy of 10 Mev abcve threshold in the center-of-momentum system the ratio of this cross section to that for pi /sup -/ + p yields p + p + n is about 5: 1. At an energy of 40 Mev above threshold this ratio hns decreased to 1: I. The total cross section for the reaction leading to the unbound final state is calculated by assuming a modified Fermi statistical model. At an energy 100 Mev above threshold, this cross section is approximately …

In this study, the Anton Webern's music is considered in two groups: that which was written before Webern adopted the twelve-tone technique, Opp 1-16, and that written in the twelve-tone technique, Opp. 17-31. This division is not intended to represent an attempt at periodization of Webern's music, for the changes of style in Op. 17 are not that significant. But the fact that Webern employed the twelve-tone technique in all the works he wrote after Op. 16 makes this a natural point of division for a study of this sort. Besides the music of Webern, two peripheral areas are included in this study. No attempt has been made at an exhaustive biography of Webern, but facts relative to his life, and impressions about the person are presented. Also, to create a proper perspective for the study of Webern's which existed during the time that Webern lived and composed, is presented.

This study is concerned with the experience of a particular company which undertook to improve its selection program through the installation of a test battery. This involved special adaptations of techniques commonly employed in industrial situations.

The purpose of this study is to determine the levels of anxiety in college freshmen and seniors from the Departments of Science and Art at North Texas State College by using the Taylor Manifest Anxiety Scale. It is hoped that the findings uncovered by this study will be of help to others interested in investigating and exploring this area.

The notion of a topological group follows naturally from a combination of the properties of a group and a topological space. Since a group consists of a set G of elements which may be either finite or infinite and since this is also common to a topological space, a question is opened as to whether or not it is possible to assign a topology to a set of elements which form a group under a certain operation. Now it is possible to assign a topology to any set of elements if no restriction is placed on the topology assigned and hence this study would be of little value from the standpoint of the group itself. If however it is required that the group operation be continuous in the topological space then a very interesting theory is developed.

It is the purpose of this study to investigate the personality patterns of a group of applicants who have been under the auspices of the Bishop of the Episcopal Diocese of Dallas and have received a psychiatric and psychological evaluation. The various aspects of their examinations will be investigated to determine what personality types have been more acceptable in this diocese and subsequent success in their vocation.

This thesis is a study of the Confederate command problem in the Trans-Mississippi West, 1861-1862.

Of the large amount of writings concerning the Civil War only a small percentage pertains to the Federal Navy's role. This is understandable since this was primarily a land war. A few of the Navy's exploits such as the capture of New Orleans, the sinking of the Alabama, the capture of the Florida in Brazilian waters, and the Trent affair received great amounts of publicity, but the majority of the naval activities were of a routine nature, each individually warranting little notice but collectively contributing immensely to the final Federal victory. The purpose of this paper is to show in detail the role of only a portion of the Navy, the West Gulf Blockading Squadron, during this struggle.
