摘要：

The breakup of a one-neutron halo nucleus is studied in the eikonal approximation. Both the nuclear and Coulomb breakup processes are taken into account. The continuum states, which are usually approximated by plane waves, are constrained to satisfy the condition of orthogonality to the bound states of the halo nucleus. Taking full account of the recoil effect, the neutron-core relative energy distribution of the breakup cross section is calculated for Be-11 and C-19 projectiles incident on C-12 and Pb-208 targets and compared to experimental data. All the data regarding the energy distribution for a Pb-208 target at beam energies of 68 and 520 MeV/nucleon are accurately reproduced, except for its peak at small relative energy. The experimental data regarding the relative energy distribution for the Be-11+(12)c system are also accurately reproduced. It is shown that use of orthogonalized plane waves leads to reduced cross sections and is necessary to account for the experimental data. The effect of the no-recoil limit is quantified.
