Local versus nonlocal $\alpha \alpha$ interactions in $3\alpha$ description of ${}^{12}$C

Y. Suzuki, H. Matsumura, M. Orabi +4

Local $\alpha \alpha$ potentials fail to describe ${}^{12}$C as a $3\alpha$ system. Nonlocal $\alpha \alpha$ potentials that renormalize the energy-dependent kernel of the resonating group method allow interpr…
