Comment on "Nucleus-nucleus total reaction cross sections"
Physical Review C, 1982In a recent article by DeVries and Peng, it was suggested that the concept of a geometric reaction cross section was not meaningful since sigma/sub R/ exceeded the geometric values for heavy nucleus-nucleus collisions. It is shown here that this conclusion is a consequence of using nuclear charge distributions, in place of the required nuclear single ...

Total reaction cross sections for 29 MeV protons
Nuclear Physics, 1964Abstract The USC proton linear accelerator is being used in a programme of measuring the energy dependence of proton total reaction cross sections. As a first step in this programme measurements were made using the full beam energy. The anticoincidence beam attenuation technique was used. The following cross sections were obtained for 29 MeV protons:

Phenomenological barrier parameters for total reaction cross section
Indian Journal of Physics, 2015A phenomenological formula for total reaction cross section is introduced for reactions induced by three types of projectiles. The formula is based on Wong’s formula in which, the barrier parameters are calculated from the Bass, Aage Winther and the Akyuz Winther potentials.

Study of the total reaction cross section via the reaction dynamical model
Physical Review C, 1993New calculations for the total reaction cross sections (${\mathrm{\ensuremath{\sigma}}}_{\mathit{R}}$) are carried out within the framework of nuclear transport theory combined with the optical limit of the Glauber theory. The average nucleon-nucleon collision number is obtained based on the nuclear transport theory.

Eikonal expansion for total cross sections of heavy ion reactions
Physical Review C, 1993We study the validity and convergence of the eikonal expansion for the calculation of total [sigma][sub [ital t]] and total reaction [sigma][sub [ital R]] cross sections in the case of low-energy heavy-ion collisions. Investigations are performed by considering a few typical optical potentials, varying the incident energy from 10 MeV/nucleon to 300 MeV/

Measurement of total reaction cross sections of exotic neutron-rich nuclei
Physical Review Letters, 1987Total reaction cross sections of neutron-rich nuclei from C to Mg in a thick Si target have been measured by the detection of the associated \ensuremath{\gamma} rays in a 4\ensuremath{\pi} geometry. This cross section strongly increases with neutron excess, indicating an increase of as much as 15% of the reduced strong absorption radius with respect to

30–300 MeV proton-nucleus total reaction cross sections
Physical Review C, 2011A functional form has been used to analyze proton total reaction cross sections on stable and unstable target nuclei. For proton or incident nuclei energy per nucleon in the range between 30 and 300 MeV, the parameter values in this functional are interpreted in terms of the nuclear-matter distribution by using reliable total reaction cross-sectional ...

Analysis of the 3He -nucleus total reaction cross-section
The European Physical Journal A, 2011Working within the framework of the Coulomb-modified Glauber model, we analyze the total reaction cross-section ( $ \sigma_{{R}}^{}$ for 3He -particles from 9Be , 12C , 16O , 28Si , 40Ca , 58, 60Ni , 112, 116, 120, 124Sn , and 208Pb at 96.4, 137.8, and 167.3MeV.

Study of the total reaction cross section via QMD
Chinese Physics C, 2013This paper presents a new empirical formula to calculate the average nucleon-nucleon (N-N) collision number for the total reaction cross sections (σR). Based on the initial average N-N collision number calculated by quantum molecular dynamics (QMD), quantum correction and Coulomb correction are taken into account within it.
