The 3He(n,2p)2n and the 4He(n,2p)3n cross-sections are being measured as a means to explore the Δ++ contribution to the nuclear wave function. The incident neutron beam ranged between 200 and 500 MeV. Scattered protons passed through magnetic spectrometers centered 45º to the right and left of the beam line. Each spectrometer consisted of a thin ΔE scintillator, a drift chamber, a permanent bending magnet, a drift chamber, and a detection barrier of three stacked scintillators.
