Original e- Capture Cross Sections for Hot Stellar Interior Energies

The nuclear electron capture reaction possesses a prominent position among other weak interaction processes occurring in explosive nucleosynthesis, especially at the late stages of evolution of massive stars. In this work, we perform exclusive calculations of absolute e(-)-capture cross sections using the proton-neutron (pn) quasi-particle random phase approximation. Thus, the results of this study can be used as predictions for experiments operating under the same conditions and in exploring the role of the e(-)-capture process in the stellar environment at the pre-supernova and supernova phase of a massive star. The main goal of our study is to provide detailed state-by-state calculations of original cross sections for the e(-)-capture on a set of isotopes around the iron group nuclei (Si-28, S-32, Ti-48, Fe-56, Zn-66 and Zr-90) that play a significant role in pre-supernova as well as in the core-collapse supernova phase in the energy range 0 <= E <= 50 MeV.
