Halo Structure Of C-19 Via The (p,d) Reaction

Abstract

We have investigated the heaviest one-neutron halo candidate C-19 nucleus. Few-body model calculations of cross section angular distributions for the C-19(p,d)C-18 reaction, together with the test calculations carried out for the C-17(p,d)C-16 reaction, at a low incident energy are presented for different possible halo-neutron configurations. We show that there is a clear distinction between in particular ${\ell }_n=0$ and ${\ell }_n=2$ halo transfers. The sensitivity of the cross sections to the assumed C-19 single neutron separation energy is discussed.
