Distorted-wave calculations of autoionization rates and dielectronic capture strengths of Cu-like Pb ion

A relativistic distorted-wave approximation is used to calculate the autoionization rates and dielectronic capture strengths for Cu-like Pb ion. The calculated results show that autoionization rates varies regularly with the effect of spectator electron. Autoionization rates and dielectronic capture strengths of two other high-Z elements Au and Ta for comparison are also calculated. The comparison shows good agreement between the present calculation and the theoretical results of the relative parameter potential method, the quasi-relativistic Hartree-Fock- Relativistic method and the spin-orbit-split array modle method.
