Deformation of the N=Z nucleus 76Sr using beta-decay studies
arXiv:nucl-ex/0402001 · doi:10.1103/PhysRevLett.92.232501
Abstract
A novel method of deducing the deformation of the N=Z nucleus 76Sr is presented. It is based on the comparison of the experimental Gamow-Teller strength distribution B(GT) from its beta decay with the results of QRPA 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.
