【 摘 要 】

Synopsis The angular dependence of Wigner-Eisenbud-Smith photoionization time delay has been investigated for the nd ! e f dipole channels in atomic Zn, Cd and Hg using the relativistic random phase approximation (RRPA). The studies have been carried out also in the nonrelativistic limit. This technique enables identification of the relativistic effects on the angular dependence of photoionization time delay.
