IONIZATION AND CHARGE-TRANSFER OF ATOMIC-HYDROGEN IN COLLISION WITH MULTIPLY-CHARGED IONS

Ionization and charge-transfer cross sections of atomic hydrogen in collision with multiply charged ions are calculated for various projectile charges (Z=28) in the energy range from 1 to 400 keV/amu by the atomic-orbital close-coupling method. Many pseudostates constructed from Gaussian-type orbitals are used on the projectile and the target for the representation of continuum states. The present ionization cross sections show systematic agreement with measurements for He2+, Li3+, and C6+ impact over the entire energy range where experimental data are available. The present calculations also produce reliable consistent cross sections for excitation and electron capture simultaneously. © 1994 The American Physical Society.
