Yrast Structure Above the 9.6 s $8^+$ Isomer in $^{96}$Y Isotope
Résumé
High- and medium-spin structures have been investigated in neutron-rich 96Y isotope produced in the cold-neutron-induced fission of 235U and 241Pu targets. The study significantly extended the existing level scheme of this isotope. In the current work, particular attention was devoted to the structure which has been identified above the long 9.6 s, (8+) isomer, up to the excitation energy of 4813 keV. The angular correlation analysis, together with obtained decay pattern, allowed to propose spin values for some of the newly observed states.
