Excited states in 70Br were populated in the 40Ca(32S,pn) reaction at Ebeam=80-100 MeV and the 40Ca(36Ar, αpn) reaction at Ebeam= 145 MeV. The resulting gamma decay was detected using the Gamma-sphere array triggered by a 30-element neutron detector. The cross-bombardment allowed the unambiguous assignment of levels to 70Br, comprising a total of 32 states built both on the Jπ=O+ ground state and a previously known Jπ= 9+ isomer, which is located at an excitation energy of 2293 keV by the observation of linking transitions. The structures are discussed within the context of the two-quasiparticle plus rotor model, the IBM-4 model and the cranked Nilsson-Strutinsky formalism. The nonobservation of a doublet of J = 0, T = 1 and J = 1, T = 0 states at low excitation in 70Br is indicative that T = 0 proton-neutron pairing strength is weak in comparison to T = 1 pairing. |
