Isomeric Mirror States as Probes for Effective Charges in the Lower pf Shell

Summary, in English

Following the fragmentation of a 550 MeV u(-1)primary beam of Ni-58, time-and energy-correlated gamma decays from isomeric states in neutron-deficient nuclei in the 1f(7/2) shell have been identified using the GSI fragment separator in combination with the RISING Ge-detector array. The results on isomers in the mirror pairs Ti-43(22)21-Sc-43(21)22 (I-pi = 3/2(+) and 19/2(-)), Cr-45(24)21-Sc-45(21)24 (I-pi = 3/2(+)) and V-45(23)22-Ti-45(22)23 (I-pi = 3/2(-)) are discussed in the framework of large scale pf and sdpf shell-model calculations, the former in conjunction with isospin symmetry breaking effects with emphasis on effective charges.
