摘要：

Using the adiabatic superpromotion model of low-energy atomic collisions, a simple scaling relationship is derived for the ionization cross section of hydrogen atoms colliding with multiply charged ions. Detailed ionization-cross-section calculations for the systems H(1s)+ He2+, C6+, and O8+ have been performed and used to determine three numerical constants in the cross-section-scaling relationship. The scaled cross section represents well the available data for fully stripped ions with charge Z greater than or equal to 2 in the energy region below the cross-section maximum.
