Jian Li, J. M. Yao, J. Meng, and A. Arima
TL;DR
This paper investigates the impact of one-pion exchange current corrections on nuclear magnetic moments within relativistic mean field theory, revealing negligible effects on isoscalar moments but significant corrections on isovector moments, without improving overall agreement.
Contribution
It provides a detailed analysis of one-pion exchange current effects on magnetic moments in RMF theory, comparing with previous models and highlighting their limited impact on isovector moments.
Findings
Negligible contribution to isoscalar magnetic moments.
Significant correction to isovector magnetic moments.
Does not improve the description of nuclear isovector moments.
Abstract
The one-pion exchange current corrections to isoscalar and isovector magnetic moments of double-closed shell nuclei plus and minus one nucleon with and 41 have been studied in the relativistic mean field (RMF) theory and compared with previous relativistic and non-relativistic results. It has been found that the one-pion exchange current gives a negligible contribution to the isoscalar magnetic moments but a significant correction to the isovector ones. However, the one-pion exchange current doesn't improve the description of nuclear isovector magnetic moments for the concerned nuclei.
