Theoretical study of supernova neutrino and antineutrino scattering off the stable cadmium and lead isotopes

Abstract

In this thesis work, an extensive study of neutrino- and antineutrino-nucleus interactions is performed. The work is focused on supernova-neutrino scattering off the stable cadmium and lead isotopes. The studied nuclei are of interest for the investigations of neutrino-properties and for neutrino-detection experiments. The adopted nuclear-structure models are based on the quasiparticle random-phase approximation (QRPA) and the microscopic quasiparticle- phonon model (MQPM) and the cross-sections calculations are based on the Donnelly-Walecka formalism. The computed cross sections are folded with a two-parameter Fermi-Dirac distribution to obtain realistic estimates of the nuclear responses to supernova neutrinos. This thesis consists of two parts, an overview part and publications part. The overview part summarized the main aspect of the performed studies of the five publications presented in the second part.
