Total reaction cross section calculations in proton-nucleus scattering
Physical Review C, 1996We have developed a general semiempirical total reaction cross section formula for proton-nucleus reactions. It is applicable for all materials with nuclear charge Z greater than 5, and all proton kinetic energies from the lowest measured energies up to \ensuremath{\approxeq}20 GeV.

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

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 ...

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 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.

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.

Proton total reaction cross sections at 9.1 MeV
Nuclear Physics A, 1968Abstract Proton total reaction cross sections have been measured at 9.1 MeV for Mg, Ti, 63 Cu, 65 Cu, natural Cu and Zr using a counter anti-coincidence technique. These and earlier results have been compared with the predictions of the nuclear optical model. Good agreement has been found in the case of medium-weight nuclei.

A New Technique To Investigate Total Reaction Cross Sections
AIP Conference Proceedings, 2010We analyze the total reaction cross sections of several systems, especially weakly bound systems, by the use of a recently developed technique. We show a systematic behavior for the different systems, with larger reaction cross sections for systems with halo nuclei as projectiles.

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:

Parameterization of the total cross-section for (p,7Be) reaction
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2004Abstract The total cross-section for emission of 7Be particles in proton induced reactions has been parameterized for the proton beam energy from the threshold up to ∼20 GeV and for target mass from A = 12 to 238. The phenomenological parameterization allows to predict the cross-sections of 7Be emission with accuracy comparable to that achieved up to
