High-spin States and Shell-model Description of the Neutron-deficient Nuclei 90Ru and 91Ru

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift


High spin states in the neutron deficient isotopes Ru90 and Ru91 have been studied in the 2p2n and 2pn exit channels of the reaction Ar-36 + Ni-58 using the 149 MeV Ar-36 beam at VICKSI and the OSIRIS array. By gating the gammagamma coincidences with evaporated neutrons and protons, excited states in Ru90 were identified for the first time and the level scheme of Ru-91 was extended. In both nuclei, the level energies and branching ratios follow the predictions of shell model calculations performed within the (1g9/2,2p1/2) single-particle space.
