This book was released on 1966 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: In two counter experiments at the Princeton-Pennsylvania Accelerator, a study has been made of 2.9 BeV proton-nucleus collisions. In the first experiment differential cross sections were measured as a function of momentum for the production of Pi mesons, K(+) mesons, protons, deuterons, tritons, and helium-3 by 2.9 BeV protons striking beryllium and platinum targets. The Be data were taken at laboratory angles of 13, 30, 60, and 93 degrees relative to the direction of the incident proton beam; the Pt data, at 13 degrees and 93 degrees only. An analysis of these cross sections is given in terms of models of proton-nucleus interactions. The copious production of deuterons and tritons at all angles is found to be a complex nuclear effect. In a second experiment, antiproton production was observed in 2.88 BeV and 2.05 BeV proton-copper collisions, at a laboratory angle of 13 degrees and at a momentum of 760 MeV/c. The cross section for this antiproton production is presented, and used to estimate the distribution of Fermi momenta of the nucleons in the copper nucleus. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The antiproton annihilation process in complex nuclei was studied in photographic emulsions. When a 19.8 gr/ cm/sup 2/ LiH absorber was introduced in an existing antiproton beam, the antiproton-to-meson ratio improved by a factor of about 10, becoming 1/50,000. Thus in a single stack exposed to this improved beam, 165 antiprotons were found. These together with 20 more found in other stacks and the 36 reported in the Antiproton Collaboration Experiment'' (a total of 221 analyzed stars) are included in this analysi. From this analysis the annihilation process in complex nuclei can be interpreted to proceed as follows: The antiproton annihilates itself with one nucleon, transforming all the available energy mainly into The effects of mesons of average multiplicity 5.36 sintering time 0.28 with an occasional K-K emission of frequeney (3.5 sintering time 1.5%) per star. The mesons interact with the nucleus leaving it in an excited state. The nucleus releases the excitation energy through nucleon emission. On the average, the stars in flight have more excitation than those at rest. By the use of this experimental data and available information on pion interactions in nuclear matter, the fraction of interacting pions was deduced for the stars in flight and at rest separately. It is shown that with a better knowledge of the pion interactions in nuclear matter, antiproton annihilations can be used to investigate the nucleon distribution at the surface of the nucleus. The pion-pion angular distribution was deduced on the basis of energy-momentum conservation, by the use of the Fermi statistical model of the annihilation with Lorentz-invariant phase space. The theoretical distribution agrees with the experimental one if an adjustment of the interaction volume is made to account for the observed pion multiplicity. A strong pionpion interaction is thus unlikely. (auth).

Book excerpt: Positron Annihilation focuses on the process of positron annihilation in different environments. Partitioned into two parts with 42 chapters, the book contains the contributions of authors who have done research on the annihilation of positrons, which brought about valuable information on the properties of matter. The first part of the book deals with lengthy review articles, including a survey of the physics of positron annihilation; positron annihilation in metals and the theory involved in the process; and positron annihilation in alkali halides and ionic crystals. Positronium formation and interaction in gases, molecular substances, and ionic crystals are also given attention. Gaseous positronics and positron annihilation in condensed gases and liquids are also discussed. The second part of the book focuses on developments on positron annihilation and the direction of research on this field. The studies concentrate on positron annihilation in various crystals, metals, mercury, liquefied gases, helium, and metal oxides. Numerical representations and analyses are presented to support the processes involved. The book can best serve the interest of those who want to explore further the annihilation of positrons.
