摘要	The collisional energy transfer process Cs(6P(3/2))+M, where M=Ne, N-2, under gas cell conditions has been investigated. The Cs(6P(3/2)) state was excited by a diode laser. The direct 6P(3/2)-->6S(1/2) fluorescence and the sensitized 6P(1/2)-->6S(1/2) fluorescence as a function of quenching gas pressure were measured. For quenching by Ne only energy transfer from the electronic to translational is possible. However, in the N-2 case, energy transfer from the electronic to vibrational or rotational is important. Using a two-state rate equation model, the quenching rate coefficients for Cs(6P(3/2)) were obtained. The fine structure energy transfer rate coefficient for Ne is 1.45 x 10(-12) cm(3) center dot s(-1). By comparing the relative fluorescence intensities for Ne and N-2 case, the authors estimate that the rate coefficient for 6P(3/2)-->6P(1/2) transfer in collision with N-2 is 1.64 x 10(-12) cm(3) center dot s(-1). The quenching rate coefficient for the 6P state is 4.88 x 10(-12) cm(3) center dot s(-1).
