Abstract

The ⁸⁰Se(d, α)⁷⁸As reaction was investigated with 16.0 MeV deuterons. The ground state and nineteen excited levels of ⁷⁸As were identified up to 1.27 MeV excitation energy. Except for the level at 276 keV, all the other excited levels were previously unreported. Angular distributions were measured and compared with DWBA calculations. Unambiguous L-values could be extracted for nine transitions. The transition to the ground state of ⁷⁸As has an L = 3 character. Four levels at 276, 536, 967 and 1072 keV were tentatively assigned as J^π = (1⁺) levels. Four transitions were observed to proceed with L = 1 transfer, indicating a significant shift from the shell model description in this mass region. The configuration dependence on angular-distribution shape was examined. The measured Q-value for the ⁸⁰Se(d, α)⁷⁸As reaction is 5.755 ± 0.012 MeV.
