Neutrino Energy Loss by Electron Capture on Nucleus ⁵⁶Mn, ⁵⁶Fe, ⁵⁶Co and ⁵⁶Ni in Strong Electron Screening

Based on the p--f shell model, the neutrino energy loss rates for nucleus 56Mn, 56Fe, 56Co and 56Ni in the electron capture process are canvassed in and not in a strong electron screening. The results show that the neutrino energy loss rates for ⁵⁶Mn, ⁵⁶Fe, 56Co and 56Ni decrease about 15%, 10%, 60% and 1 order of magnitude correspondingly at the temperature T9=15 and even debase 2 orders of magnitude at the temperature T9=1.
