摘要：

The loss of kinetic energy of slow (nu = 0.3 nu(Bohr)) ions transmitted through thin carbon foils has been measured as a function of projectile charge state in the range from q = 3+ for oxygen to q = 69+ for gold ions. For the first lime, charge state dependent energy loss enhancements have been observed for Xeq+ and Auq+ at q greater than or equal to 40+, indicating strong preequilibrium contributions to the energy loss of slow, highly charged ions in solids.
