Goldkuhle, A., Fransen, C., Dewald, A., Arnswald, K., Bast, M., Beckers, M., Blazhev, A., Braunroth, T., Hackenberg, G., Haefner, G., Litzinger, J., Jolie, J., Mueller-Gatermann, C., von Spee, F., Warr, N., Werner, D., Zell, K.

Abstract

The level lifetimes of the yrast 2(1)(+), 4(1)(+) and 6(1)(+) states and an upper limit of the lifetime of the 8(1)(+) state in Ti-46 have been measured with high accuracy exploiting the recoil distance Doppler-shift method (RDDS) and using coincidences. The nuclei were populated by the fusion evaporation reaction Ca-40(Be-9, 2p1n)Ti-46 at a beam energy of E=33 MeV at the FN tandem accelerator of the University of Cologne, Germany. Lifetimes were extracted using the established differential decay curve method (DDCM).

Abstract

Lifetimes of excited states in Tc-107, Rh-109, Rh-111, and Rh-113 were measured at GANIL using the Recoil-Distance Doppler Shift method. The neutron-rich nuclei were produced in fission reactions in inverse kinematics with a U-238 beam impinging on a Be-9 target. Fission fragments were identified event-by-event in the ray-tracing spectrometer VAMOS++ and correlated with prompt gamma rays observed around the target position with the EXOGAM Ge detector array. Several lifetimes were obtained for states in the positiveparity yrast bands in the four nuclei and compared to triaxial particle-rotor calculations. The results clarify the configuration for the strongest positive-parity band in Tc-107 and suggest a gradual increase of triaxial deformation with atomic number Z, reaching almost maximum triaxiality for the neutron-rich Rh nuclei.

Abstract

The lifetimes of the 2(1)(+), the 2(2)(+) and the 3-1 states of Po-210 have been measured in the Pb-208(C-12, Be-10)Po-210 transfer reaction by the Doppler-shift attenuation method. The result for the lifetime of the 2(1)(+) state is about three times shorter than the adopted value. However, the new value still does not allow for a consistent description of the properties of the yrast 2(1)(+), 4(1)(+), 6(1)(+), and 8(1)(+) states of Po-210 in the framework of nuclear shell models. Quasi-particle Phonon Model (QPM) calculations also cannot overcome this problem thus indicating the existence of a peculiarity which is neglected in both theoretical approaches.
