Title: Structure of 14 B and the evolution of N = 9 single-neutron isotones

Abstract

We have used the 13 B( d , p ) 14 B reaction in inverse kinematics to study the properties of states in 14 B, the lightest particle-bound N = 9 isotone. The spectroscopic information, including spins, parities, and spectroscopic factors for the states observed in 14 B are used to deduce the wave functions for the low-lying negative parity ν ( sd ) levels, as well as provide information about the evolution of the effective neutron 1 s 1 / 2 - 0 d 5 / 2 single-particle energies. The data confirm that the ground and first-excited states are predominantly s wave in character and are single-neutron halo states. The effective single-particle energies are found to match the trends set by other N = 9 isotones.
