Abstract

The Coulomb breakup of one-neutron halo nuclei is studied within the postform distorted-wave Born approximation (DWBA) theory. A method of evaluation of the DWBA breakup amplitude in momentum space is presented. The theory is applied to the Coulomb breakup of the Be11 and C19 halo nuclei on Pb208 at the beam energy of 70MeVnucleon. Calculations for relative energy spectra are compared with available experimental data. Good agreement in shape is found for low relative energies. Comparison with the results obtained using a local momentum approximation to the DWBA amplitude shows that the effects of this additional approximation are substantial. The DWBA calculations are also compared to those of an adiabatic breakup theory. The two theories lead to significantly different results.
