Abstract：
According to a new electron screening theory, we discuss the beta decay rates of nuclide ⁵⁶Fe, ⁵⁶Co, ⁵⁶Ni, ⁵⁶Mn, 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/μ_e<10^8 g/cm³. However the beta decay rates would be influenced greatly for ρ/μ_e≥10^8 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.
