OSTI ID:6198713
The excitation-transfer collision Cs(5D5/2) + Cs(6S) yields CS(5D3/2) + Cs(6S) was studied. The upper 5D5/2 state was excited by a c-w dye laser tuned to the one photon, quadrupole-allowed 6S yields 5D5/2 transition. Since the direct 5D yields 6P fluorescence could not be detected with our apparatus we monitored instead the cascade 6P yields 6S fluorescence. The ratio of 6P 1/2 to 6P3/2 fluorescence contains information on the collisional mixing that takes place in the 5D levels but also includes a significant contribution from mixing in the 6P levels. This latter contribution could effectively be subtracted out using the results of a second experiment in which a tunable cw diode laser was used to pump the 6P3/2 state, and the same fluorescence ratio monitored. The 5D mixing cross section obtained, 70 A, is significantly larger than previous indirect determinations.
