Abstract

Data on the fragmentation of ${}^{12, 14}{Be}$ on ${}^{12}C$ at 56 and 65 MeV per nucleon have been obtained. The ${}^{12}{Be}$ fragments from the breakup of ${}^{14}{Be}$ display both a narrow longitudinal momentum distribution and a distinctive angular distribution that is consistent with an extended neutron ‘‘halo’’ in this nucleus. This is the first experiment in which both longitudinal and transverse fragment momentum distributions of exotic nuclei have been simultaneously measured.
