Abstract:
The isospin mixing was deduced in the compound nucleus Zr80 at an excitation energy of E∗=54 MeV from the γ decay of the giant dipole resonance. The reaction Ca40+Ca40 at Ebeam=136 MeV was used to form the compound nucleus in the isospin I=0 channel, while the reaction Cl37+Ca44 at Ebeam=95 MeV was used as the reference reaction. The γ rays were detected with the AGATA demonstrator array coupled with LaBr3:Ce detectors. The temperature dependence of the isospin mixing was obtained and the zero-temperature value deduced. The isospin-symmetry-breaking correction δC used for the Fermi superallowed transitions was extracted and found to be consistent with β-decay data.
