Distributions of the parallel momentum of [sup 10]Be fragments from the breakup of 63[ital A]MeV [sup 11]Be have been measured for [sup 9]Be, [sup 93]Nb, [sup 181]Ta, and [sup 238]U targets. The distributions have similar narrow widths with a mean value of 43.6[plus minus]1.1 MeV/[ital c] FWHM, and agree with a theoretical momentum distribution for the valence neutron in [sup 11]Be. The breakup mechanisms do not appear to distort the parallel momentum distribution of the [sup 10]Be core. These findings support the existence of a one-neutron halo in [sup 11]Be and the use of the parallel momenta of the heavy breakup products as a reliable probe of halo neutron momenta.
