This chapter presents predictions for the magnetic dipole and Gamow-Teller transitions in various light nuclei ( \(A=7\text{--}17\) ). From the NCCI calculations, we obtain predictions for both the impulse approximation (IA) and meson-exchange current (MEC) corrections. We investigate the convergence of the many-body calculation, and try to understand the systematic dependence of the calculated results on the chiral EFT parameters. The new results are compared with earlier calculations performed with other many-body methods and interactions, as well as with experimental data where available.

摘要

This chapter presents predictions for the magnetic dipole and Gamow-Teller transitions in various light nuclei ( \(A=7\text{--}17\) ). From the NCCI calculations, we obtain predictions for both the impulse approximation (IA) and meson-exchange current (MEC) corrections. We investigate the convergence of the many-body calculation, and try to understand the systematic dependence of the calculated results on the chiral EFT parameters. The new results are compared with earlier calculations performed with other many-body methods and interactions, as well as with experimental data where available.
