Magnetic moments of C isotopes studied with antisymmetrized molecular dynamics

We studied the magnetic dipole moments μ of even-odd C isotopes, ranging from proton-rich to neutron-rich nuclei, with antisymmetrized molecular dynamics (AMD). The results are in good agreement with the experimental data. In the ⁹C ground state the total intrinsic spin of the protons is found to be nonzero (S_p≠0), which is unusual in even-odd nuclei. The interesting point is that the spin-orbit force breaks slightly the coupling off of intrinsic spins of the even nucleon group in isospin T=3 / 2 nuclei. This result is consistent with the newly measured μ data that, when combined with ⁹Li data, indicate an unusual 〈σ〉 value larger than unity. A μ moment -1.05μ_N of ¹⁷C is theoretically predicted. We also show a good reproduction of E2 transition data.
