Abstract
We have used the B()B reaction in inverse kinematics to study the properties of states in B, the lightest particle-bound isotone. The spectroscopic information, including spins, parities, and spectroscopic factors for the states observed in B are used to deduce the wave functions for the low-lying negative parity levels, as well as provide information about the evolution of the effective neutron single-particle energies. The data confirm that the ground and first-excited states are predominantly wave in character and are single-neutron halo states. The effective single-particle energies are found to match the trends set by other isotones.
