Abstract: | According to a new electron screening theory,we discuss the beta decay rates of nuclide 56Fe,56Co,56Ni,5GMn,56Cr and 56V with and without strong electron screening (SES).The results show that SES has only a slight effect on the beta decay rates for ρ/μe < 108 g/cm3.However the beta decay rates would be influenced greatly for ρ/μe ≥108 g/cm3.Due to SES,the maximum values of the C-factor (in %) on beta decay rates of 56Fe,56Co,56Ni,56Mn,56Cr and 56V is of the order of 95.03%,35.02%,98.05%,80.33%,98.30% and 98.71% at T9=4.0 and 98.83%,98.89%,99.65%,10.32%,4.10% and 40.21% at T9=7.0,respectively. |
