Abstract

Evidence for chirality in nuclei has been found in N similar to 75 isotopes in the A similar to 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 similar to 57-63, Z similar to 43-45 region is another promising island of triaxiality. The present experimental study with the Euroball gamma-ray array, using the reaction Zr-96(C-13, p2n) at 51 MeV is aimed to search for chirality in Rh-106. Channel selection of Rh-106 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 similar to 300 keV above the yrast band, has been found. The two structures show the characteristic properties of the chiral phenomenon.
