Abstract
Reduced transition strengths of the deexciting transitions from the first two excited states in were measured in a relativistic Coulomb excitation experiment at the GSI Helmholtz center. The radioactive ion beam was produced by fragmentation of a primary beam on a target followed by the selection of the reaction product of interest via the GSI Fragment Separator. The beam hit a secondary target with an energy of approximately 145 MeV/nucleon. An array of high-purity germanium cluster detectors and large-volume scintillator detectors were employed for -ray spectroscopy at the secondary target position. The Lund-York-Cologne Calorimeter was used to track the outgoing ions and to identify the nuclear reaction channels. For the two lowest energy excited states of the reduced transition strengths have been determined. With these first results the nucleus is now, together with , the only neutron-deficient odd- shell nucleus in which experimental transition strengths are available. The experimental values are compared to results of shell-model calculations which describe simultaneously mirror-energy differences and transition-strength values of mirror pairs in the shell in a consistent way.
