$$g$$ factor of the exotic $$N=21$$ isotope $$^{34}$$Al; Probing the $$N=20$$ and $$N=28$$ shell gaps at the border of the "island of inversion"

An exotic nucleus $$^{34}$$Al was produced at GANIL, and its absolute value of the $$g$$ factor was measured for the first time. Based on the value and the $$beta$$ decay branching, the ground state of $$^{34}$$Al is most liekly to be $$4^-$$. By comparing the shell model calculation for the $$g$$ factor, it turns out that the ground state of $$^{34}$$Al cannot be described unless a significant excitation from the $$sd$$ to $$pf$$ shells is taken into account. Thus, the nucleus belongs to the so-called "island of inversion." We performed the Monte Carlo shell model calculation, showing that this $$g$$ factor is sensitive not only to the $$N=20$$ gap but also the $$N=28$$ gap.
