摘要：

Kinetic energies of Ar+ ions desorbed by double photoionization at 100 eV from argon layers (from 2 to 20 monolayers) condensed on platinum are measured and compared with predicted values. Unexpected low kinetic energies are explained by a relaxed Coulomb repulsion mechanism. The weakness of the high-kinetic-energy ion signal is considered to be due to the noncrossing of the bound and repulsive potential-energy curves involved in the desorption model.
