Abstract
A method for calculating dynamic dipole polarisabilities and two-photon photoionisation cross sections using the R-matrix approach to atomic processes is presented. The method is illustrated by an application to the calculation of the dynamic dipole polarisability of the ground state of neon, and the results are compared with those calculated omitting the R-matrix surface terms. Values for the static polarisability and the 2p6 1So- 2p53s 1P1 oscillator strength of neon are also given.Keywords
