Resumé

An attempt is made to estimate stopping powers for swift nonrelativistic heavy ions in the velocity range where projectile screening is significant. In contrast to existing tabulations and computer codes, our calculations take account of the fact that Bohr's classical approach is superior in this velocity regime to the Bethe theory. A theoretical scheme for estimating stopping powers at a fixed projectile charge, developed recently by one of us, has been expanded so as to account for charge equilibrium. Both target and projectile excitation/ionization are taken into account. The agreement with available experimental data appears promising in the considered velocity range (v0<v<2Z1v0) considering the fact that shell and polarization corrections still need to be incorporated.
