Inelastic neutrino-nucleus reaction cross sections are studied focusing on the neutral current processes. Particularly, we investigate the angular and initial neutrino-energy dependence of the differential and integrated cross sections for low and intermediate energies of the incoming neutrino (or antineutrino). Contributions coming from both, the vector and axial-vector components of the corresponding hadronic currents have been included. The initial and final state nuclear wave-functions have been calculated in the context of the Quasi-particle Random Phase Approximation (QRPA) tested on the reproducibility of the low-lying energy spectrum (up to about 5 MeV) of the studied nuclei. The results presented here refer to the nuclear isotopes 16O and 98Mo. As it is well known, O plays a significant role in supernova evolution phenomena and Mo is used as a target in the MOON neutrino experiment at Japan.

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.

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.
