High spin states and multiquasiparticle excitations in odd-odd 114,116Sb nuclei

Excited states of 114, 116Sb have been investigated in the 111, 113Cd (7Li,4nγ) reactions. In both level schemes, two independant parts have been exhibited with, mainly, a negative parity band based on 8- or 7- states and a positive parity sequence based on a 11+ state. The interpretation of the significant levels has been performed in the core-particle model and in term of quasiparticle configurations mixing, this last approach being able to give a kind of unified description of the whole spectrum.
