Complex-coordinate study of photoionisation of Li and Na using one-electron pseudopotentials

Abstract

The method of complex coordinates is a useful tool for studying many bound-free transitions. Recently the method has been used to calculate photoabsorption cross sections of one- and two-electron atoms. The authors have performed calculations on the photoabsorption of lithium and sodium by the complex-coordinate method using different pseudopotentials. The results from the different pseudopotentials are compared with other theoretical and experimental results.
