Angular correlation functions for the {sup 4}He({pi}{sup {plus minus}},{pi}{sup {plus minus}{prime}}{ital t}){ital p} reaction at the incident energy {ital T}{sub {pi}}=180 MeV and at four pion scattering angles have been measured. The {sup 4}He({pi}{sup {plus minus}},{pi}{sup {plus minus}{prime}}{ital t}){ital p} data complement previous {sup 4}He({pi}{sup {plus minus}},{pi}{sup {plus minus}{prime}}{ital p}){ital 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. |
