Dynamic screening by projectile electrons in heavy ion collisions

OSTI ID:6576271
Anaysis of recent helium and oxygen ion data has shown that the degree of screening of the ion charge can be represented approximately by a model based on the spatial distribution of bound electrons. This screening model is introduced into the binary encounter approximation to account for screening for projectile electrons, and calculated single and double differential cross sections are compared for He/sup +/, He/sup 2 +/ ionization of argon and O/sup 5 +/ ionization of oxygen. Cross sections for ionization including contributions from both target and projectile are calculated. (GHT)
