Abstract
The 3He(n,2p)2n and 4He(n,2p)3n cross-sections are being measured as a means to explore the Δ++ component of the nuclear wave function. The incident neutron beam ranges between 250 and 800 MeV. Scattered protons on beam right pass through magnetic spectrometers which measure the momentum of the proton. The spectrometer consists of a thin ΔE scintillator, two drift chambers, two permanent magnets and finally two thin scintillators. On beam left, a horizontal ΔE scintillator array in front of a vertical proton scintillator array also detects scattered protons.
