Experimental transition probabilities for lines arising from the 4d5p and 4d5d configurations of ZrIII

Relative transition probabilities for 120 lines arising from the 4d5p and 4d5d configurations of ZrIII were determined from measurements of emission-line intensities in a laser-produced plasma. The experiment was carried out with Cu-Zr alloy with a Zr content lower than 13% in order to have an optically thin plasma. Transition probabilities were placed on an absolute scale by using theoretical lifetimes, line-strength sum rules and Boltzmann plot. Comparison of the present experimental results with the available theoretical data is made.
