Calculations are carried out for momentum distributions of neutrons fr
om fragmentation of He-8. To reproduce the corresponding experimental
data, we use the five-body (alpha + 4n) cluster-orbital shell-model wa
ve function of He-8, consider the n-target scattering in the Glauber a
pproach, and take into account the n + He-6 final-state interaction at
the resonance He-7.
