Description
An isolated system of four neutrons is studied in the SAMURAI experiment at the Radioactive-Ion Beam Factory at RIKEN [1]. The key reaction 8He(p,pα)4n in inverse kinematics populates the final state of four neutrons through a prompt quasi-free-scattering process close to 180 degrees in the p-α centre-of-mass frame. The resulting energy spectrum of the free 4n system reveals a distinct peak-like structure with positive energy centered at 2.4 MeV in addition to a more broad distribution associated with the continuum. The details of the experimental method and the analysis results will be presented along with the further perspectives of studying multi-neutron systems.
