Abstrakt: Evidence for chirality in nuclei has been found in N ∼ 75 isotopes in the A ∼ 130 mass region. This phenomenon is a signature of triaxiality in nuclei and there is a clear need to study other regions of the Segre chart to see if further examples can be found. Potential Energy Surface (PES) calculations suggest that the N ∼ 57–63, Z ∼ 43–45 region is another promising island of triaxiality. The present experimental study with the Euroball γ-ray array, using the reaction 96Zr(13C, p2n) at 51 MeV is aimed to search for chirality in 106Rh. Channel selection of 106Rh was done using the charged-particle array DIAMANT. The yrast level scheme, studied previously in fusion-fission work, has been confirmed and extended in the present study. In addition, a new strongly coupled band, lying at an excitation energy of ∼ 300 keV above the yrast band, has been found. The two structures show the characteristic properties of the chiral phenomenon. © 2004 American Institute of Physics [ABSTRACT FROM AUTHOR]
