Description
A novel method of deducing the deformation of the N=Z nucleus Sr76 is presented. It is based on the comparison of the experimental Gamow-Teller strength distribution B(GT) from its β decay with the results of quasi-random-phase approximation calculations. This method confirms previous indications of the strong prolate deformation of this nucleus in a totally independent way. The measurement has been carried out with a large total absorption gamma spectrometer, 'Lucrecia', newly installed at CERN-ISOLDE
