QUANTUM AND CLASSICAL PATH CALCULATIONS OF THE TOTAL CROSS-SECTION FOR HE-2)+NE(2P(6),S-1)-]HE+(S-2)+NE(2P(5)3S(1),P-2) WITH COLLISION ENERGY FROM 20 TO 70.9 EV((S)

In this paper we have calculated total quantum cross sections as a fun ction of collision energy with the range of 20 to 70.9 eV and have com pared these results with those obtained by using the Classical Path ap proximation and the Landau-Zener method applied to the He+Ne system. W e obtain a very satisfactory agreement between quantum and classical p ath total cross sections and we have also found oscillations for the t ransition probabilities with collision energy close to the threshold w hich were not found in a previous work.
