Fusion reaction of a weakly bound nucleus with a deformed target

Abstract

We discuss the role of deformation of the target nucleus in the fusion reaction of the 15 C + 232 Th system at energies around the Coulomb barrier, in which 15 C is a well-known one-neutron halo nucleus. To this end, we construct the potential between 15 C and 232 Th with the double folding procedure, assuming that the projectile nucleus is composed of the core nucleus, 14 C, and a valence neutron. In addition, we also take into account the coupling to the one-neutron transfer process to the 14 C + 233 Th configuration. We show that such calculation simultaneously reproduces the fusion cross sections for the 14 C + 232 Th and the 15 C + 232 Th systems, implying an important role of the transfer coupling in fusion of neutron-rich nuclei.

Signatures of elongated and compact configurations in the fusion barrier distribution of deformed nuclei

“…The process of nuclear fusion has always attracted significant attention due to its intriguing nature and broad implications in various fields, both theoretically and experimentally [1][2][3][4][5][6][7][8][9][10][11][12]. Its exploration holds immense importance, ranging from the synthesis of superheavy nuclei (SHN) and nuclear energy development to gaining insights into nuclear astrophysics investigations [3,13].…”
