The soft-spheres model of nuclear reaction cross sections incorporating tapered density distributions is used to evaluate nucleon mean free paths and transparencies at intermediate energies. Comparison with similar calculations employing uniform density distributions shows the latter to give misleading results that nevertheless have been used in recent years as evidence that the physics of the nucleon–nucleon interaction within nuclei is incompletely understood.

Reaction Cross Sections

Calculations of the 6,8 He +28 Si total reaction cross-sections at intermediate energies are performed on the basis of the Glauber–Sitenko microscopic optical-limit model. The target-nucleus density distribution is taken from the electron-nucleus scattering data, and the 6,8 He densities are used as they are derived in different models. The results of the calculations are compared with existing experimental data. The effects of the density tails of the projectile nuclei as well as the role of shell admixtures and short-range correlations are analyzed.
