Using both recoil and fast-particle spectrometers, the reaction π^-+⁴He→π^-+³H+x has been measured for triton momenta in the region 0.24-0.60 GeV/c. The experimental spectra are presented as functions of triton momentum and angle and of mass of the unmeasured object. In the theoretical analysis it is assumed that the final state can be reached via quasielastic scattering from N^*3H states and via N^* productions from the p³H state of helium. The most credible of three investigated p³H wave functions requires one percent of N^*3H states in the mass range 1.08-1.80 GeV/c².
