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 {sup 11}Be and {sup 19}C halo nuclei on {sup 208}Pb at the beam energy of {approx}70 MeV/nucleon. 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.
