Relative transition probabilities for 18 lines of Zn II (11 measured for the first time) were determined from the emission-line intensities in a laser-produced plasma. The experiment was carried out using Cd–Zn alloy with a Zn content under 10% in order to obtain optically thin plasma. Oscillator strengths were placed on an absolute scale by using experimental lifetimes, line-strength sum rules and Boltzmann plot. A comparison has been conducted between present experimental results, the data available and new calculations reported in this work, as well as a study of the plasma conditions.
