- Abstract
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 ( 28 Si, 32 S, 48 Ti, 56 Fe, 66 Zn and 90 Zr) 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.
