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

Abstract

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