Cluster folding analysis for 15N ions scattered by 13C and 27Al targets

Motivated by two well-known cluster structures for the 15N nucleus, 13C + d and 11B + α, which appear at excitation energies (Ex) = 16.159 and 10.992 MeV, respectively, the angular distributions (ADs) for 15N nucleus elastically scattered in the field of two medium-mass targets, namely, 13C and 27Al are investigated within the cluster folding model. Reasonable agreements between the measured and calculated ADs data for the considered nuclear systems are obtained, which validates the cluster structure description of the 15N ground-state, configured as a core (13C/11B) with a valence particle (d/α) orbiting the core. We aim at quantitatively investigating the 13C + d and 11B + α cluster structure of the ground state of 15N nucleus, providing new insight into the fundamental nuclear interactions.
