Influence of the potential energy surface on the cross sections for deeply inelastic transfer reactions induced by heavy ions

Abstract Large differences are observed in the cross sections for deeply inelastic reactions involving the transfer of several charges from 40 Ca and 40 Ar projectiles to the same rare-earth targets. The cross sections for four and six charge transfers from projectile to target are enhanced for 40 Ca incident ions. These differences are qualitatively explained by considering that the drift paths in the ( Z , A ) plane are governed by a static potential energy surface which describes the composite system. Shell corrections have been included in the calculation of this potential energy surface.
