L. Axelsson et al., Deriving the angular variation of p(parallel to)-distributions for halo neutrons with robust statistics, NUCL PHYS A, 679(3-4), 2001, pp. 215-230
The longitudinal neutron momentum distribution from core breakup of Li-11 a
nd Be-11 have been measured at 29.9 MeV/u and 38.5 MeV/u, respectively. Sep
arate measurements on Li-9 and Be-10 allowed extraction of the halo neutron
distribution. The shapes of the distributions are analyzed using robust an
d descriptive statistics, For both isotopes the shape is changing with angl
