    Abstract We have measured the cross section for π− + 4 He → π− + 3 H+p at 5 GeV /c incident pion momentum. The momentum transfer to the pion was in the region 0.005≦|t ππ|≦0.15 (GeV/c)2 and the triton recoil momentum in the region 0.24 ≦ p t ≦ 0.60 GeV/c. A theoretical model including final-state interactions has also been developed. Strong final-state interactions prohibit a direct extraction of the relative proton-triton bound-state wave function. Nevertheless, we are able to conclude that the wave function remains positive for relative proton-triton momenta up to at least 0.6 GeV/c. This result questions the relevance of wave functions derived from the helium electromagnetic form factor.
