Abstract
Peripheral fragmentation of a 287 MeV/nucleon beam of the halo nucleus incident on a carbon target has been studied in a fragment-neutron coincidence experiment. The momentum distribution of the fragments gives access to the momentum distribution of the removed neutron in . From the shape of the distribution, the contribution to the mixture of and components in the ground-state wave function was determined to be . The angular correlation between the knocked out neutron and the one from the decay of shows a skew distribution signaling interference of these two different parity states.
