The authors analyze a proposed measurement of a high-energy reaction on the neutron-rich nucleus He. After the sudden knockout of the particle (He) by a proton in inverse kinematics all final-state particles are detected. This gives access to the final-state interaction between the two neutrons, thereby allowing extraction of the scattering length, which pertains to charge-symmetry breaking in the nucleon-nucleon interaction. The focus is on the theoretical uncertainties in the extraction of the scattering length from the relative-energy distribution of the two neutrons.
