Transition probabilities of four Cd lines and the lifetime of Cd I 51D2

An induction coupled argon plasma has been used to measure transition probabilities in metal atoms. This work is described and transition probability measurements on several lines of cadmium I are reported. These transitions with their measured transition probabilities are as follows: 51D2 to 51P1, (59+or-8)*106 s-1; 61D2 to 51P1, (5.5+or-1.2)*106 s-1; 71D to 51P1, (4.7+or-1.5)*106 s-1; 53D1 to 53P2, (4.3+or-0.5)*106 s-1.
