Nuclear magnetic moment of the neutron-rich nucleus
Résumé
The ground-state magnetic dipole moment of the neutron-rich isotope has been measured via -ray-detected nuclear magnetic resonance () spectroscopy by using a spin-polarized secondary beam of produced from the primary beam. From the present measurement, the factor has been determined. Based on the comparison of this value with Schmidt values, we unambiguously confirm the configuration with spin and parity assignments for the ground state, suggested by previously reported studies. Consequently, the magnetic moment has been determined as . The obtained experimental magnetic moment is in good agreement with the predictions of the shell-model calculations using the USD, YSOX, and SDPF-M interactions as well as random phase approximation (RPA) calculations. This observation indicates that the nucleus in its ground state does not manifest any anomalous structure and is not influenced by the proximity of the drip line.
