A theoretical study of photoionization parameters of Hg atom confined in a spherical shell potential has been carried out using the relativistic random phase approximation. It is found that confinement, correlation and relativistic effects all bring significant and separate changes in the 6s photoionization cross-section, and also in the photoelectron angular distribution. © 2007 IOP Publishing Ltd.

Confinement, correlation and relativistic effects on the photoionization of 6s subshell of Hg

Journal of Physics: Conference Series

A theoretical study of dipole and quadrupole Cooper minima, along with dipole and nondipole photoelectron angular distribution parameters, in Hg 6s has been performed using the relativistic-random-phase approximation methodology. It is found that the Cooper minima affect the angular distribution parameters dramatically. In addition, the results show that the angular distribution parameters are extremely sensitive to both relativistic and correlation effects (interchannel coupling). © 2007 The American Physical Society.
