Transition Probabilities of Some High Lying States of Cd II

Experimental transition probabilities for 38 transitions with origin of the 4d106p, 7p, 8p, 4f, 5f and 4d95s5p electron configurations of Cd II have been measured. Relative values of the spectral line intensities have been determined in a laser-produced plasma. The experiment was carried out with pure cadmium target as well as with several Zn-Cd alloys, where the Cd content was lower than 10%. Theoretical lifetime values of Cd II excited states have been obtained in this work using Hartree-Fock wavefunctions and multiconfiguration mixing in an intermediate coupling in order to place the experimental data of branching ratio in an absolute scale. The Boltzmann plot and plasma temperature in LTE conditions is also used for obtaining the absolute transition probabilities. Comparison of the present experimental and theoretical results with the previously published data has been made.
