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+HCs+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.
