Theoretical test for chirality s in negative parity states of Rhodium (Rh)-105

The chirality in the negative-parity levels in 105Rh nucleus has been examined by the theoretical model Interacting Boson-Fermion Model (IBFM). The IBFM succeed in prediction the negative parity excitation energy in the 105Rh nucleus. Including high-j orbits in the IBFM calculations or not gave nearly the same behavior. This nucleus could have static chirality but not vibration chirality. The negative parity bands dose not show the ideal chiral symmetry.
