Abstract
A novel method of deducing the deformation of the nucleus is presented. It is based on the comparison of the experimental Gamow-Teller strength distribution from its 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.
