Multiphoton detachment rates have been obtained for Na[sup -] using the R-matrix Floquet (RMF) approach. In the low intensity limit agreement has been found with recent theoretical calculations of the total photodetachment cross section. At intensities of 10[sup 10] W cm[sup -2] two-photon above threshold detachment rates are presented and similarities with earlier calculations in Li[sup -] are discussed. Also at this intensity, three-photon rates are investigated for energies ranging from below the 3p [sup 2]P° threshold to the 4p [sup 2]P° threshold. © 2000 American Institute of Physics.
