Numerical methods must be used in order to obtain photoionization cross-sections for non-hydrogenic levels. The atomic data required to calculate them is huge so self-consistent calculations increase computing time considerably. Analytical potentials are a useful alternative because they avoid the iterative procedures typical in self-consistent models. In this work, we present a relativistic quantum calculation of photoionization cross-sections for isolated ions based on an analytical potential to obtain the required atomic data, which is valid both for hydrogenic and non-hydrogenic ions. Comparisons between our results and others obtained using either widely used analytical expressions for the cross-sections or more sophisticated calculations are done. | URI: | http://hdl.handle.net/10553/46061 | ISSN: | 0022-4073 | DOI: | 10.1016/j.jqsrt.2004.07.001 | Source: | Journal of Quantitative Spectroscopy and Radiative Transfer [ISSN 0022-4073], v. 91, p. 393-413 |
