Abstract
The single-nucleon knockout reactions Be-9(B-14, B-13 + gamma)X and Au-197( B-14, B-13 + gamma)X, at an incident energy of 60 MeV per nucleon, have be en used to probe the structure of B-14 and of the core fragment B-13. A dom inant 2s configuration is deduced for the neutron in the ground state of B- 14. The longitudinal momentum distribution for this state is consistent wit h "neutron halo" structure. Spin assignments for B-13 excited states at 3.4 8 and 3.68 MeV are proposed based on the observed spectroscopic factors for one-neutron removal.
