Description
Summary:Neutrinos and their interactions with nuclei have attracted a great deal of attention, since they play a fundamental role in nuclear physics, cosmology and various astrophysical processes, especially in the dynamics of core-collapse supernova-nucleosynthesis. Since there are very few experimental data available on charged current neutrino-nucleus reactions, modelling these provides the relevant input for supernova simulations. In this work, the total cross sections as well as the neutrino event rates are calculated in the charge current neutrino and antineutrino scattering off super(114)Cd and super(116)Cd isotopes at neutrino energies E sub([nu]) < 100 MeV. These isotopes are the contents of several detectors of ongoing experiments with multiple neutrino physics goals. Such cross section calculations provide us with significant information regarding the range of efficiency of these isotopes in low-energy neutrino searches. Transitions to excited nuclear states are calculated in the framework of a quasiparticle random-phase approximation. The contributions from different multipoles are shown for various neutrino energies. Flux-averaged cross sections are obtained by convolving the cross sections with the Fermi-Dirac distribution of supernova neutrinos.
