Abstract
The Glauber model for two-body scattering is applied to elastic and dissociation scattering of single-neutron halo nuclei. We give estimates of the relative importance of the double scattering contributions. They slowly decrease with the increasing size of the halo wavefunction, but are never negligible in practical cases. We propose an efficient expansion of these terms allowing us to propose a method for performing accurate analysis of experimental data. The method is valid for both elastic scattering and dissociation. Finally, on the same footing, we discuss the parallel momentum distribution obtained from inclusive dissociation experiments. Most of our results are based on Gaussian parametrizations but they are expected to remain valid in a more general framework.
