Isomeric mirror states as probes for effective charges in the lower pf shell

Following the fragmentation of a 550 MeV u −1 primary beam of 58 Ni, timeand energy-correlated γ decays from isomeric states in neutron-deficient nuclei in the 1f7/2 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 43 Ti 21 – 43 Sc 22 (I π = 3/2 + and 19/2 − ), 45 Cr 21 – 45 Sc 24 (I π = 3/2 + ) and 45V22– 45Ti23 (I π = 3/2 − ) are discussed in the framework of large scale
