摘要：
Angular correlation functions for the He-4(pi+/-, pi+/-'t)p reaction at the incident energy T(x)=180 MeV and at four pion scattering angles have been measured. The He-4(pi+/-, pi+/-'t)p data complement previous He-4(pi+/-, pi+/-'p)t results by greatly extending the available range of proton emission angles. We calculate angular correlation functions of the cross sections with three different quasifree knockout models, and we show that direct triton knockout is crucial to an understanding of the data.
