Title: Energy dependence of proton-nucleus reaction cross sections

Abstract

Reaction-cross-section data for proton-nucleus scattering up to 1 GeV have been analyzed in a black-disk model. Simple phenomenological relations are derived, which make it possible to predict the energy dependence of proton-nucleus reaction cross sections. The relations require only the total cross sections in nucleon-nucleon scattering and the matter densities of the proton and the target nucleus.

  • The 800-MeV ( p,p') inclusive proton spectra at forward angles are considered. A plane-wave impulse approximation is used to calculate quasifree nucleon knockout and quasifree isobar production. When the quasifree peaks are normalized to data, we find that the integrated cross section for the two processes can account for the total reaction cross section.
  • It is found that measuring the energy distribution of emitted particles at two different incident energies and two reaction cross sections is sufficient to obtain the energy dependence of a reaction cross section when it is knowm that a compound nucleus is formed. The cross sections obtained are a function of the excitation energy of the residual nucleus. They are the usual reaction cross sections at zero excitation energy when the assumption is made that the reaction cross section does not vary with the excitation energy of the target nucleus. By comparing the reaction cross sections thus obtained with measuredmore » nonelastic cross sections, the compound elastic cross section may also be obtained. An example using this method is given in which two measured energy distributions and two measured cross sections were used to obtain the energy dependence of the reaction cross section of nickel in the 2.5- to 7-Mev energy range.

  • In this paper are presented tables of all directly measured total reaction cross sections and total cross sections for protons interacting with all complex nuclei ({sup 2}H and heavier) for proton energies up to 1 GeV. Some semiempirical fittings to the data are also included. 9 refs., 2 figs., 3 tabs.
  • We show that while the mass number dependences of the proton inclusive cross section measured in collisions of near-equal mass nuclei at 800 MeV/nucleon can, over a wide range of energies, be reproduced reasonably well by simplified multiple scattering models based on independent nucleon nucleon collisions, definite discrepancies show up at very high transverse momentum. Possible reasons for these deviations are discussed.
