Lifetime measurements in mirror nuclei super(31)S and super(31)P: A test for isospin mixing

Using the super(20)Ne + super(12)C fusion-evaporation reaction at E sub(20)Ne = 33 MeV and the multidetector array GASP in conjuction with the EUCLIDES charged particle detector, angular correlations of coincident pairs of gamma transitions and lifetimes in mirror nuclei super(31)S and super(31)P ha...

Description
Summary:Using the super(20)Ne + super(12)C fusion-evaporation reaction at E sub(20)Ne = 33 MeV and the multidetector array GASP in conjuction with the EUCLIDES charged particle detector, angular correlations of coincident pairs of gamma transitions and lifetimes in mirror nuclei super(31)S and super(31)P have been measured at the Piave-Alpi accelerator of the Laboratori Nazionali di Legnaro. A comparison of the determined B(E1) strengths of the analog mirror 7/2 super(-) arrow right 5/2 super(+) transitions indicates the presence of a violation of isospin symmetry.
