Levels of 107Rh

• The levels in 107Rh have been investigated via the γ-rays following the β− decay of 3.75 min 107Ru. The ruthenium activity was produced in the thermal neutron-induced fission of 239Pu 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 108Pd(d, 3He) reaction was investigated at Ed = 50 MeV to study the proton-hole states in 107Rh. From the comparison of the measured angular distributions with DWBA calculations l-transfers and spectroscopic factors were deduced. The obtained level scheme of 107Rh is discussed and compared with neighbouring nuclei and with recent calculations in the framework of the interacting boson-fermion (IBFM-1) model.
