Abstract

Strengths and Stark-effect widths of the Sni and Snii lines prominent between 3200 and 7900 \AA{} are measured with a spectroscopic shock tube. Absolute strengths of 17 ionic lines are obtained with estimated (22-50)% accuracy and conform to appropriate quantum-mechanical sum rules. Relative transition probabilities for nine prominent neutral tin lines, normalized to radiative-lifetime data, are compared with other experiments and theoretical predictions. Parameters for Stark-effect broadening are measured over a range of plasma electron densities. Broadening data [with accuracies of (15-35)%] for one neutral and ten ionic lines of tin are compared to theoretical predictions.
