Spectroscopy of 13,14B via the one-neutron knockout reaction
Abstract
The single-nucleon knockout reactions 9Be(14B,13B+γ)X and 197Au(14B,13B+γ)X, at an incident energy of 60 MeV per nucleon, have been used to probe the structure of 14B and of the core fragment 13B. A dominant 2s configuration is deduced for the neutron in the ground state of 14B. The longitudinal momentum distribution for this state is consistent with ``neutron halo'' structure. Spin assignments for 13B excited states at 3.48 and 3.68 MeV are proposed based on the observed spectroscopic factors for one-neutron removal.
