AbstractAbstract
[en] The most neutron-deficient isotopes in the N = Z region are an important source of information on the neutron-proton interaction far off stability. The isotopes in this region are characterized by an extreme sensitivity of the deformation to the isospin variations. Here the structure of deformed shells are favoring the high spin states the lifetime of which being sufficient long to be observed after flight time of the order of the microsecond. The study of the decay of this isomeric states permits to approach the structure of the first excited levels of this isotopes. Recent experiments at GANIL with the SISSI - LISE 3 spectrometer were performed to study the neutron deficient nucleus 66As. This nucleus was produced in the fragmentation of 70 MeV/u 78Kr primary beam in a nickel target. Two new isomeric states have been observed. From the observed γ transitions a decay scheme is proposed
