Notes:
Hg(7 1S0→7 3S1) spin changing transfer and Hg(7 3S1) total deactivation, induced by collisions with Hg, H2, D2, He, and Xe, are studied. Hg vapor, pure or mixed with foreign gas, was excited to the 7 1S0 state by absorption of two photons from a pulsed dye laser. Measurement of the relative intensities of the fluorescence from the 7 1S0 and 7 3S1 states allowed the determination of the collisional rate constants. The velocity-average cross sections thus measured for Hg(7 3S0)+M→Hg(7 3S1)+M are 1.32, 0.11, and 0.28 A(ring)2 for Hg, H2, and D2, respectively. The total deactivation cross sections for 7 3S1 are 4.7 and 9.6A(ring)2 for H2 and D2, respectively.
