Abstract
The possible photoreactions leading to the formation of “laser snow” in cell experiment
by laser irradiation of Cesium atoms to the (7p) level will be analyzed through crossed
beam experiment. A single collision process would be excluded if an activation barrier
was present in the inverse ground state reaction CsH+H→Cs+H2; accurate ab initio
calculations exclude the existence of such a barrier. The ionic state Cs+ + H2− is suggested to make possible the electronic into vibrational energy transfer in the
perpendicular collision.
