2009, Master of Science, University of Toledo, Physics.
Information on the makeup of the solid material in space as well as on the production of elements in our Galaxy and beyond may be gained through analysis of ultraviolet absorption from ions in interstellar clouds. High quality oscillator strengths are needed to convert the amount of absorption into an accurate abundance from data acquired with the Hubble Space Telescope and the Far Ultraviolet Spectroscopic Explorer. Lifetimes from my beam-foil experiments for ultraviolet transitions in Cu II are reported. The Cu II results for the 1358.773 Å line (3d10 1S0 - 3d4p 1P1o) provide further evidence for a short lifetime for the upper level of interest. Additional results for transitions that can repopulate the upper state of interest indicate the data are not affected by these cascades. My measured lifetime of 1.37 ± 0.04 ns is in excellent agreement with the most recent experimental results and is consistent with theoretical values. My determination of 0.273 ± 0.008 for the oscillator strength is in very good agreement with the recommended value given by Morton (2003) and the theoretical results of Donnelly et al. (1999).
