摘要：

The deactivation processes of Cd(5 3P2) by H-2 and D2 were studied by employing pulsed laser techniques. The cross sections for the intramultiplet relaxation to produce Cd(5 3P1) and Cd(5 3P0) were determined as follows: Cd(5(3)P2)+H2-->Cd(5(3)P1)+H2; 6.3, Cd(5(3)P2)+H2-->Cd(5(3)P(0)+H2; 1.0, Cd(5(3)P2)+D2-->Cd(5(3)P1)+D2; 4.4, Cd(5(3)P2)+D2-->Cd(5(3)P0)+D2; 0.9, in units of 10(-16) cm2 at 630 K. The cross sections for the overall deactivation of Cd(5 3P2) by H-2 and D2 were determined to be 9.8 X 10(-16) cm2 and 6.9 X 10(-16) cm2, respectively. These values are compared with the calculated results based on a semiclassical curve crossing mechanism. It is suggested that electronic-to-rotational energy transfer without sharp resonances plays an important role in the deactivation of Cd(5 3P2).
