Abstract

Previous analytical formulas in the Glauber model for high-energy nucleus-nucleus collisions developed by Wong are utilized and extended to study Antiproton-nucleus annihilations for both high and low energies, after taking into account the effects of Coulomb and nuclear interactions, and the change of the antiproton momentum inside a nucleus. The extended analytical formulas capture the main features of the experimental antiproton-nucleus annihilation cross sections for all energies and mass numbers. At high antiproton energies, they exhibit the granular property for the lightest nuclei and the black-disk limit for the heavy nuclei. At low antiproton energies, they display the effect of the antiproton momentum increase due to the nuclear interaction for the light nuclei, and the effect of the magnification due to the attractive Coulomb interaction for the heavy nuclei.

Antiproton-nuclei annihilation in the momentum range 0.70-2.50 GeV/c

Journal Article Kuzichev, V; Lepikhin, Yu; Smirnitsky, V - Physics of Atomic Nuclei

The results of the measurements of the antiproton annihilation cross sections on the nuclei Be, C, Al, Fe, Cu, Cd, and Pb at the momentum range 0.70-2.50 GeV/c are presented. The A-dependence of the cross sections is described by the formula {sigma}{sub 0}A{sup {alpha}}. The behavior of the parameters {sigma}{sub 0} and {alpha} does not agree with optical model in the Glauber approach. It is suggested that such a behavior is a result of the Coulomb influence on the annihilation processes at the low momenta. The description of cross sections using formula {sigma} = A{sup 2/3}(a{sub 0} + a{sub 1}Zmore »« less
Interaction of low-energy antiprotons with nuclei

Journal Article Dal'karov, O; Karmanov, V - Sov. J. Particles Nucl. (Engl. Transl.); (United States)

The first results on the interaction of antiprotons with nuclei obtained in experiments at the Low Energy Antiproton Ring (LEAR) put into operation at CERN at the end of 1983 are presented and analyzed. In contrast to the case with protons of the same energy (approx.50 MeV), elastic p-bar--nucleus scattering manifests a pronounced diffractive nature and is described well by the Glauber--Sitenko approximation taking into account the Coulomb interaction. The effective nuclear radius determined from antiproton scattering is significantly (1.5 times for /sup 12/C) larger than the radius determined from proton and electron scattering. We discuss the possible reasons formore »« less
A STUDY OF THE ANTIPROTON ANNIHILATION PROCESS IN COMPLEX NUCLEI

Technical Report Kalogeropoulos, T.

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 antiprotonmore »« less

ANTIPROTON-NUCLEON ANNIHILATION PROCESS

Journal Article Chamberlain, H; Goldhaber, G; Jauneau, L; ... - Physical Review (U.S.) Superseded in part by Phys. Rev. A, Phys. Rev. B: Solid State, Phys. Rev. C, and Phys. Rev. D

Work was continued on antiproton interactions in photographic emulsions. Most of the data come from an exposure at the Bevatron to an enriched antiproton beam of 700 Mev/c momentum. An analysis of 221 antiproton stars is presented, 95 of which occurred in flight.

Strong absorption and noneikonal effects in antiproton--nucleus scattering

Journal Article Zavarzina, V; Sergeev, V - Sov. J. Nucl. Phys. (Engl. Transl.); (United States)

In connection with the successful description of the low- and medium-energy antiproton--nucleus interaction within the framework of the Glauber-Sitenko theory we consider the role of strong absorption in these processes. On the basis of an analytic method of calculations we study the connection between the eikonal scattering amplitude, the total cross section, and the reaction cross section with the model of a black nucleus with diffuse boundary. We present examples showing how the effective radius of the black nucleus for the antiprotons is determined in terms of geometrical parameters of the nuclear density and of the parameters of the elementarymore »« less
