Description

The possible role of isobar degrees of freedom in nuclear structure accounting for departures from the symmetry properties of mirror nuclei is investigated. Specifically for T = 1/2 conjugate pairs, we evaluate the corresponding mirror Gamow-Teller beta decays. In a simple model description, admixtures of isobar components at the few percent level can accommodate the experimentally observed asymmetries in mirror pairs of masses A=13 and 17. (author)
