Determination of neutron-neutron scattering length from the nd-breakup reaction: Experimental and theoretical aspects
A new experiment to determine the length of neutron-neutron scattering from the nd-breakup reaction is described. The experiment was performed on the 13–60 MeV neutron beam in the meson factory of the Institute of Nuclear Research Russian Academy of Sciences. In addition to the standard models, a new dibaryon model was used for the first time in the treatment of two- and three-nucleon interactions. Wave-packet continuum discretization was used to describe the dynamics of three-body scattering processes correctly.
