Abstract
Differential cross-section and vector-analyzing-power data were obtained for an incident deuteron energy of 12.5 MeV for the 76,78,80,82Se(d, p) 77,79,81,83Se reactions. The results are compared with the predictions of the DWBA theory to determine l-values, spins, parities and spectroscopic factors of the resolved states. Magnetic spectrograph measurements were made to determine the excitation energies of the states studied as well as for a number of additional levels in each isotope. A precise determination of the 82Se(d, p) 83Se Q-value was also made, yielding a value of 3.5934±0.0030 MeV. Spin and parity assignments have been made to 16 states in 77Se, 22 states in 79Se, 17 states in 81Se, and 15 states in 83Se. In addition, tentative spin assignments were made to one state in 79Se and to three states in 83Se. A sum-rule analysis was carried out and comparisons made to previous work and to the predictions of the simple pairing theory. The results are in general agreement with the Coriolis-coupling model calculations of Heller and Friedman.
