  We investigate the structure of the neutron rich nucleus $^{14}$B through
studies of its breakup in the Coulomb field of a heavy target. The breakup
amplitude is calculated within an adiabatic as well as finite range DWBA
theories of breakup reactions. Both these formalisms allow the use of realistic
wave functions for the relative motion between the fragments in the ground
state of the projectile. The longitudinal momentum distributions of $^{13}$B
(ground state) following the breakup of $^{14}$B on a heavy target at beam
energy of 60 MeV/nucleon, calculated using two possible ground state
configurations of $^{14}$B, have been compared with the recent data. The data
seem to favour $^{13}$B(${3\over 2}^-)\otimes2s_{1/2}$ as the possible ground
state configuration of $^{14}$B with a spectroscopic factor close to unity. We
give our predictions for the neutron angular distributions and the relative
energy spectra in the one-neutron removal reaction of $^{14}$B.
