The 23Πg-13∑u+ diffuse fluorescence spectrum around 5730? for K2 dimer excited by 4415.6? CW Isser line was obtained. The collision-induced enhancement effect of the maximum intensities Idiff of the diffuse spectrum versus the pressure P ot buffer gas Ar was studied experimentally. The energy transfer processes of C1Πu-23Πg was showed by stable collision model. The Idiff-P relation was deduced and a satisfactory fitting for the experimental data was obtained by use of this model. This fitting showed that the energy crossing rate and collision-induced transfer rate could be obtained by this model with some alternations of the experimental setup.
