PAIR PRODUCTION WITH CAPTURE, AN IMPROVED THEORETICAL DESCRIPTION USING THE RELATIVISTIC CONTINUUM-DISTORTED-WAVE EIKONAL-INITIAL-STATE MODEL R.J.S. Lee, J.V. Mullan, J.F. McCann and D.S.F. Crothers The School of Mathematics & Physics The Queen's University of Belfast, Belfast BT7 1NN, N. Ireland Experimental cross sections for e+/e- pair production in the collision of fully stripped La ions with thin foils of copper, silver or gold have been published by Belkacem et al. The results of theoretical calculations using the Relativistic Continuum-Distorted-Wave Eikonal-Initial-State (RCDW-EIS) model are compared with experiment and previously published theoretical data.
