    COLLISIONAL DEPOLARIZATION OF ZEEMAN COHERENCES IN THE 133^{133}Cs 6p2P3/26p^{2}P_{3/2} LEVEL WITH ARGON MOLECULES: TWO-PHOTON POLARIZATION SPECTROSCOPY

    Author Institution: Miami University, Physics Department, Oxford, OH 45056An experimental investigation of the Cs 6s2S1/26p2P3/210s2S1/26s^{2}S_{1/2}\rightarrow6p^{2}P_{3/2}\rightarrow10s^{2}S_{1/2} double resonance two-photon polarization spectrum has been made. In the investigation, a linear polarization degree was measured to extract the alignment depolarization cross section in the cesium 6p2P3/26p^{2}P_{3/2} level due to collisions between ground-level argon and excited 6p2P3/26p^{2}P_{3/2} cesium atoms over the Zeeman coherences. The spectra show strong depolarization of the Cs 6p2P3/26p^{2}P_{3/2} level. The measured alignment depolarization cross section value of 186186 (58)A˚2 \AA^2 is in good agreement with experiment and theoretical predictions
