Joshi, P., Carpenter, M. P., Fossan, D. B. et al. (6 more authors) (2007) Effect of ? Softness on the Stability of Chiral Geometry: Spectroscopy of 106Ag. Physical Review Letters, 98 (10). pp. 102501-1. ISSN 1079-7114
A study of the nucleus 106Ag has revealed the presence of two strongly coupled negative-parity rotational bands up to the 19- and 20- states, respectively, which cross each other at spin I~14. The data suggest that near the crossover point the bands correspond to different shapes, which is different to the behavior expected from a pair of chiral bands. Inspection of the properties of these bands indicates a triaxial and a planar nature of rotation for the two structures. Possible causes for this may be understood in terms of a shape transformation resulting from the large degree of softness of 106Ag. These data, along with the systematics of the odd-odd structures in the mass 100 region, suggest that softness has marked implications for the phenomenon of nuclear chirality.
