The loss of kinetic energy of slow (v=0.3v{sub 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 time, charge state dependent energy loss enhancements have been observed for Xe{sup q+} and Au{sup q+} at q{ge}40+ , indicating strong preequilibrium contributions to the energy loss of slow, highly charged ions in solids. {copyright} {ital 1997} {ital The American Physical Society}
