Distributions of parallel and transverse momenta for {sup 7}Be fragments formed in the breakup of {sup 8}B have been measured at 41A MeV. The {ital p}{sub {parallel}} distributions are narrow (81{plus_minus}4 and 62{plus_minus}3MeV/{ital c} FWHM for Be and Au targets, respectively), comparable to those of neutron halo nuclei. Reaction mechanisms influence the {sup 7}Be momentum distributions, so they do not directly reflect the valence proton momentum wave function. We present reaction models that reproduce the distributions. {copyright} {ital 1996 The American Physical Society.}
