Abstract

The lifetime of the 9/2⁺ state of ⁶⁵Cu, at 2534 keV, has been measured by fast timing techniques, in order to establish wether such state arises from a weak coupling between a p_3/2 proton and the 3⁻ octupole vibration at 3.56 MeV in the ⁶⁴Ni core. The ⁶⁵Cu nucleus was populated by the reaction ⁷Li + ⁶⁴Ni at 32 MeV, at the Horia Hulubei National Institute of Physics and Nuclear Engineering (NIPNE) in Bucharest, and its γ-decay was detected by the ROSPHERE array. The measured lifetime coresponds to a B(E3) reduced transition probability to the ground state equal to 8.89 W.u., in agreement with theoretical predictions in the weak coupling limit.
