Abstract
The properties of excited states in the neutron-rich nucleus have been investigated using the reaction with an 80 MeV beam provided by the IFIN-HH Laboratory, Bucharest. Discrete -ray decays from excited states have been measured using the hybrid HPGe- array RoSPHERE. The current work identifies a number of previously unreported low-lying nonyrast states in as well as the first measurement of the half-life of the yrast state of 302(50) ps. This is equivalent to a W.u. and intrinsic quadrupole deformation of . The experimental results are compared with Hartree-Fock-Bogoliubov–interacting-boson-model calculations and are consistent with a reduction in a quadrupole collectivity in Os isotopes with increasing neutron number.
