Sažetak
The shape transition in the neutron-rich Os isotopes is studied by investigating the neutron rich 196Os nucleus through in-beam gamma-ray spectroscopy using a two-proton transfer reaction from a 198Pt target to a 82Se beam. The beam-like recoils were detected and identified with the large-acceptance magnetic spectrometer PRISMA and the coincident gamma rays were measured with the AGATA demonstrator. The de-excitation of the low-lying levels of the yrast-band of 196Os were identified for the first time. The results are compared with state-of-the-art beyond mean-field calculations, performed for the even-even 188, 198Os isotopes. The new results suggest a smooth transition in the Os isotopes from a more axial rotational behaviour towards predominately vibrational nuclei through triaxial configurations. An almost perfect gamma-unstable/triaxial rotor yrast-band is predicted for 196Os which is in agreement with the experimentally measured excited states.
