Abstract

Cadmium atoms in the 53P0,1,2 states could be detected when a mixture of Cd vapor and He was irradiated with the output of a XeCl laser at 308 nm. It was revealed that CdHe collision complexes are excited to one of the repulsive levels correlating with Cd(53P2) + He. Cd (53P0,1) atoms are formed by collisions with He. The cross sections for the intramul- tiplet relaxation of Cd(53P2) to produce Cd(53P1) and Cd(5 3P0) by He were determined to be 8.6 × 10−20 and 7.5 × 10 −21 cm2, respectively. These values are compared with the results of a close-coupling calculation.
