Abstract
77Br has been investigated by the reaction64Ni(16O,p2nγ) at 60 MeV. The following mean lives (in parentheses) have been determined by the recoil distance Doppler shift method (energies in keV): 161.9 (718±50 ps), 575.2 (14.2±2.1 ps), 639.0 (14.1±0.8 ps), 782.0 (4.3±0.9 ps), 790.1 (6.2±0.8 ps), 1,273.2 (4.0±1.0 ps), 1,303.0 (4.0±1 ps), 1,480.8 (0.6 ±0.2 ps). The resultingB(E2) values are compared with rotor plus particle calculations. Nuclear reaction64Ni(16O,p2nγ)E 0=60 MeV; measuredE γ, recoil distance Doppler shift; deducedT 1/2. Enriched target, Ge(Li).
