Abstract
The individual lifetimes of three low-lying states in the proton-decaying well-deformed rotational band in the second minimum of the N = Z nucleus Cu-58 were determined. Doppler-shift attenuated gamma -ray lineshapes were analyzed following the fusion-evaporation reaction C-40,(Mg-24,1 alpha 1p1n)Cu-58 and using the EUROBALL gamma -ray spectrometer coupled to ancillary detector systems. The deduced transitional quadrupole moments confirm the predicted increase of deformation towards the bottom of the band. The gamma decay-out strength hints towards a nonstatistical pattern.
