Coulomb Breakup Of Be-11 And C-19

We investigate the Coulomb part of the one-neutron removal cross section in breakup reactions of the neutron rich nuclei Be-11 and C-19. Approximate Coulomb breakup amplitudes an derived from two distinct theoretical viewpoints. One of these uses an approximation to the distorted-wave Born approximation. The other assumes an adiabatic treatment of the projectile excitation to the low energy continuum. Both approaches include approximately the finite range of the interaction between the breakup fragments and so can treat non-s-wave projectiles. Calculations are analyzed and compared with available experimental data for total one-neutron removal cross sections, neutron angular distributions, heavy charged fragment momentum distributions. and excitation energy spectra for breakup on high Z targets.
