Abstract
A kinematically complete experiment on the reaction
2H(n, p2n) is described, in which both outgoing neutrons were detected at a lab angle of 30° so as to enhance their final state interaction in a region far from interfering reaction mechanisms. The data were analysed in terms of the Watson-Migdal model to obtain two independent values for the neutron-neutron scattering length. We find
a
nn to be −13.3
+3.8
−3.1 fm (from a comparison with measurements of p-d breakup), and − 17.5
−4.5
+4.0 fm (from the shape of the relative neutron energy spectrum), thus validating the Watson-Migdal model in this kinematic region.
