Аннотация
The
np scattering length was obtained in a kinematically complete experiment devoted to studying the nd-breakup reaction at low energies of neutrons from the RADEX channel of Institute for Nuclear Research, Russian Academy of Sciences. In this experiment, two neutrons were detected on different sides of the primary-beam axis. The scattering-length values of
1.1 fm and
fm obtained at
and 11 MeV, respectively, from a comparison of the experimental dependence of the nd-breakup reaction yield on the relative energy of the np pair with the results of a simulation differ significantly from the corresponding values found in an experiment that studied free np scattering. This is indicative of an efficient enhancement of np interaction in the presence of a third nucleon.
