The velocity dependence of the rate constant for free-ion production via the Rydberg electron-transfer reaction K({ital np})+SF{sub 6}{r arrow}K{sup +}+SF{sub 6}{sup {minus}*} has been investigated at intermediate {ital n}. The data provide evidence of a postattachment interaction between the product ions in which internal energy from the SF{sub 6}{sup {minus}*} ion is converted into translational energy. A similar conclusion is reached from measurements of the velocity and angular distributions of the product K{sup +} ions.
