BOHRS ADIABATIC CRITERION AND EFFECTIVE CHARGE OF HEAVY-IONS

Bohr's adiabatic criterion indicates that a projectile of velocity v w hich collides with target atoms is stripped of those electrons with or bital velocities smaller than v. Using this criterion, and the Hartree -Fock wave functions for the description of the momentum distribution of projectile electrons, we show that the number of stripped electrons follows a universal scaling law. The utility of this law for represen ting the effective charge of heavy ions is discussed. Copyright (C) 19 96 Elsevier Science Ltd
