Effective Mass of $\alpha$-Cluster in ${}^{12}$C Nucleus

Igor Filikhin, Abdennaceur Karoui, Branislav Vlahovic

Based on the effective-mass concept, we perform the Faddeev calculations for a low-lying spectrum of 3$\alpha$ states in ${}^{12}$C nucleus. A three-body potential is used to describe the…
