摘要：

Molecular-dynamics simulations are performed to calculate the energy of krypton atoms and excimers sputtered by "cavity ejection" upon trapping of excitons at the surface of the solid. Calculated shifts in the atomic lines of the photoabsorption spectrum are compared with experimentally observed values to test the accuracy of the interaction potentials. In contrast to previous work on argon, only the excimer formed in the singlet state was ejected with a kinetic energy of 0.11 eV. Since none of the long-lived (10(-6) sec) triplet-state excited atoms or excimers are ejected, there should be no "cavity-ejection" contribution to the luminescence plume like that observed in argon.
