Description
The levels in 109Rh have been investigated via the γ-rays following the β- decay of 34.5 s 109Ru. The ruthenium activity was produced in the thermal neutron-induced fission of 249Cf and separated chemically from the fission product mixture with the on-line centrifuge system SISAK. The emitted γ-rays were studied by γ singles and γγ(t) coincidence measurements. In addition, the 110Pd(d,3He) reaction was investigated at Ed = 50 MeV to study the proton-hole states in 109Rh. From the comparison of the measured angular distributions with DWBA calculations l-transfers and spectroscopic factors were deduced. The level scheme of 109Rh that was obtained is discussed and compared with neighbouring nuclei and with recent calculations in the framework of the interacting boson-fermion model (IBFM-1). An interpretation of the observed candidates for intruder states as a rotational band built upon the [431] Nilsson configuration is proposed. (orig.)
