Abstract
The He2+＋H Impact Ionization process is investigated using a continu um distorted wave method with the eikonal initial-state(CDW-EIS) approximation.The total,single- and double-differential cross sections are obtained in the projectile energy ranges from 30keV/u to 2000keV/u.The total cross sections are compared with the existing theoretical and experimental data.When the projectile energy is larger than 100keV/u,our results are in good agreement with the experimental measurements,while about 50% less than experimental data in the lower energy range.The ionization mechanism of soft-collisions,electron captured to continuum states and binary-encounter collisions are also displayed.
