Abstract
Spin-averaged static exchange potential and modified semiclassical exchange potential have been used in the distorted-wave Born approximation to calculate the triple differential cross section of Mg (3 s2) in the coplanar symmetric geometry. The calculations have been carried out at impact energies ranging from (R=) 1.78 to 8.84 times the first ionization potential for Mg. The effect of post-collision interactions has been included by making use of the Gamow factor introduced by Whelan [Phys. Rev. A 50, 4394 (1994)]. Present results have been compared with recent experiments of Murray [Phys. Rev. A 72, 062711 (2005)] and are found to be in excellent agreement with the same except for the lowest impact energy (that is, for R=1.78 times above the first ionization potential). © 2007 The American Physical Society.
