Giant dipole radiation and isospin purity in highly excited 32S nuclei

Abstract

We have extracted the degree of isospin mixing in 32S at the excitation energy of 58 MeV by comparing measured and calculated high-energy γ-ray spectra from the statistical decay of the 32S and 31P compound nuclei formed in heavy-ion fusion reactions. We have found that the isospin mixing is small in agreement with theoretical predictions.
