Abstract
We study cold collisions between trapped ions and trapped atoms in the semiclassical (Langevin) regime. Using ions confined in a Paul trap and Yb atoms in a magneto-optical trap, we investigate charge-exchange collisions of several isotopes over three decades of collision energies down to (). The minimum measured rate coefficient of is in good agreement with that derived from a Langevin model for an atomic polarizability of 143 a.u.
