Spatial separation of outer neutrons in 11Li.

Abstract

Calculated neutron momentum distributions are presented for the reaction {sup 11}Li+{sup 12}C{r_arrow}{sup 9}Li+2{ital n} at a beam energy of 280 MeV/nucleon. Different assumptions were made about the average distance between the two outer (halo) neutrons of the {sup 11}Li projectile. The purpose was to discover whether the measurement of neutron momentum distributions and fragment cross sections could provide information about the distribution of distance between the two neutrons. {copyright} {ital 1996 The American Physical Society.}
