Description
Momentum distributions of the recoil target ion and the ejected electron have been calculated for 75-keV H2++He collisions by applying the classical trajectory Monte Carlo (CTMC) and the continuum-distorted-wave-eikonal-initial-state (CDW-EIS) theory. A qualitative agreement was found between the calculated centroid values of the momentum distributions and the corresponding experimental data published recently by An et al. [Phys. Rev. A 63, 030703 (2001)]. The presence of postcollision interaction effects in the momentum distributions was analyzed repeating the CTMC calculations with a short-range model potential between the electron and the projectile ion as a function of the interaction length. The role of two-center effects was investigated by comparing the CDW-EIS results with those obtained in the first-Born approximation
