The 108 Pd nucleus has been studied with the 100 Mo( 11 B, p2nγ) reaction at 43 MeV incident energy. γ − γ − t, γ −γ− charged particle coincidences and directional correlation ratios were measured using the γ spectrometer formed by four Compton suppressed HPGe detectors and a 4π charged-particle ancillary detector system. The struture of the bands was interpreted within the framework of the cranked shell model and total Routhian calculations.

The 105 Rh nucleus has been studied by in-beam γ spectroscopy with the heavy-ion fusion-evaporation reaction 100 Mo(11 B, α2nγ) at 43 MeV. A rich variety of structures was observed at high and low spin, using γ − γ − t and γ − γ− particle coincidences and directional correlation ratios. Four magnetic dipole bands have also been observed at high spin. Two of them are nearly degenerate in excitation energy and could be chiral partners, as predicted by Tilted Axis Cranking calculations.

The high-spin structures of the 108 Pd nucleus have been studied with the 100 Mo( 11 B, p2nγ ) reaction at 43 MeV incident energy. γ -γ -t, γ -γ -charged-particle coincidences and directional correlation ratios were measured using the SACI-PERERE γ spectrometer formed by four Compton suppressed HPGe detectors and a 4π charged-particle ancillary detector system. Recent results for the γ -vibrational band and the νh 11/2 ⊗ ν(g 7/2 , d 5/2 ) negative parity structures have been confirmed and complemented. A new band tentatively based on the second lowest (νh 11/2 ) excitation has been observed.
