Abstract

Single and multiphoton detachment rates have been calculated for Na- using the R-matrix Floquet approach. In the low-intensity limit the results are in agreement with other recent calculations of the total photodetachment cross section. At intensities of 1010 W cm-2 two-photon detachment rates are presented and similarities with earlier calculations in Li- are discussed. Three-photon rates are also presented at this intensity and are compared and contrasted with the single-photon case since both involve resonance structure with 1Po symmetry. The influence of resonances such as the 4s2 1Se doubly excited state and excitations of the residual atom are also considered.
