چکیده

Nucleon total reaction and neutron total cross sections to 300 MeV for 12C and 208Pb, and for 65 MeV scattering spanning the mass range, are predicted using coordinate space optical potentials formed by full folding of effective nucleon-nucleon interactions with realistic nuclear ground state densities. Good to excellent agreement is found with existing data.

Theoretical and Experimental K+ Nucleus Total and Reaction Cross Sections from the KDP-RIA Model

The 5-dimensional spin-0 form of the Kemmer-Duffin-Petiau (KDP) equation is used to calculate scattering observables [elastic differential cross sections (dσ/dΩ), total cross sections (σTot), and reaction cross sections (σReac)] and to deduce σTot and σReac from transmission data for K ++ 6Li, 12C, 28Si, and 40Ca at several momenta in the range 488− 714 MeV/c. Realistic uncertainties are genera...

Nucleus-nucleus reaction cross-sections calculated for realistic nuclear matter distributions within the Glauber-Sitenko approach

Abstract.Basing on the thickness (profile) function, previously obtained for the realistic Fermi type distribution of nucleons in nuclei, calculations are made of the microscopic eikonal phases of the nucleus-nucleus scattering and the total reaction crosssections. In so doing, the phase is deduced to the one-dimensional integral provided that the Gaussian density distribution for the projectil...

A method for calculating proton-nucleus elastic cross-sections.

Recently [Nucl. Instr. and Meth. B 145 (1998) 277; Extraction of in-medium nucleon-nucleon amplitude from experiment, NASA-TP, 1998], we developed a method of extracting nucleon-nucleon (N-N) cross-sections in the medium directly from experiment. The in-medium N-N cross-sections form the basic ingredients of several heavy-ion scattering approaches including the coupled-channel approach develope...

PHOTON-NUCLEUS TOTAL CROSS SECTIONSt

Quantitative predictions for the energy and A dependence of the nuclear photoabsorption cross section and inelastic electron-nucleus scattering are given. In general each nucleon does not contribute equally to the total photon-nucleus cross section when coherent contributions of photoproduced hadrons are taken into account. At low energies (E Y N 1 BeV) the cross sections are proportional to nu...

Fe b 19 97 Progress in the Development of Global Medium - Energy Nucleon - Nucleus Optical Model Potentials

Two existing global medium-energy nucleon-nucleus phenomenological optical model potentials are described and compared with experiment and with each other. The first of these employs a Dirac approach (second-order reduction) that is global in projectile energy and projectile isospin and applies to the target nucleus 208 Pb. Here the standard S-V (isoscalar-scalar, isoscalar-vector) model has be...
