Full Faddeev-type calculations are performed for one-neutron knockout reaction of {sup 14}Be on proton target at 69 MeV/nucleon incident energy. Inclusive transverse momentum distributions for the outgoing ({sup 12}Be+n) system and semi-inclusive cross sections are presented. A significant proton-core single scattering contribution emerges where the valence neutron has nonzero angular momentum relative to the core. This indicates that distorted-wave impulse approximation is inadequate and the complete multiple scattering series must be taken into account for the considered reaction. The magnitude of the semi-inclusive cross section at quasifree scattering conditions is a clear signature of the angular momentum of the valence nucleon.
