Abstract
The R-matrix theory of atomic photoionisation using the Dirac Hamiltonian is formulated in a similar way to that used in the non-relativistic case. Both the initial atomic bound state and the final atomic continuum state are expanded in terms of R-matrix bases. The method is programmed for a general atomic system and then used to calculate the total photoionisation cross sections of ground-state neon atoms.Keywords
