| Abstract: | The measurement of the collisional cross section for the process Li*(2P)+Cs(6S)→Li(2S)+Cs*(5D) are reported. The technique of resonant Doppler-limited two-photon laser excitation with thermionic detection is applied. The population density of the Cs*5D state is probed by photoionization, and the signals of the Cs(6S)→Cs*(5D) and the Li(2S)→Li*(2P) transitions are compared. The value for cross section of 30 Å2 is measured, with an accuracy of 45%. |
