A Method for Unambiguous Detection of a Hypothetical Bound Two-Neutron System

An experiment is proposed aiming at the unambiguous detection of mass A = 2 neutral particles via elastic scattering and neutron exchange reactions on protons in a plastic scintillating fibre detector. Di-neutrons would be produced in ordinary π − absorption at rest on 3He together with tagging protons. The basic advantages of the proposed process are the strict collinearity and opposite, and constant momenta of hypothetical di-neutrons and recoiling particles in the LAB reference frame. Moreover, the detection cross sections (2 n + p → p + 2 n; 2 n + p → d + n) are calculable with three-nucleon codes based on 1 a nn dependent nn interactions.
