Prediction and evaluation of magnetic moments in T=1/2, 3/2, and 5/2 mirror nuclei

摘要

The Buck-Perez analysis of mirror nuclei magnetic moments has been applied on an updated set of data for T = 1/2,3/2 mirror pairs and attempted for the first time for T = 5/2 nuclei. The spin expectation value for mirror nuclei up to mass A = 63 has been reexamined. The main purpose is to test Buck-Perez analysis effectiveness as a prediction and-more importantly-an evaluation tool of magnetic moments in mirror nuclei. In this scheme, ambiguous signs of magnetic moments are resolved, evaluations of moments with multiple existing measurements have been performed, and a set of predicted values for missing moments, especially for several neutron-deficient nuclei is produced. A resolution for the case of the 57Cu ground-state magnetic moment is proposed. Overall, the method seems to be promising for future evaluations and planning future measurements.
