Abstract:The nuclei Y-85 and Y-86 (were studied in two series of experiments conducted by using the heavy-ion reactions Ge-76(N-14, 4n)Y-86 and Cr-52(Cl-37, 2pxn)Y-85,Y-86. The analysis of double and triple coincidences of gamma rays along with the investigation of angular distributions led to the extension of the level schemes of the Y-85 and Y-86 nuclei to spins and excitation energies higher than observed in previous experiments. In addition, a few new levels with low spins and excitation energies were identified in both nuclei. fit order to better understand the nuclear structure of these isotopes. shell-model calculations were carried out considering a valence space formed by the proton and neutron orbitals f5/2, p3/2, P1/2, and g9/2.
