The damping mechanisms of the {Delta}(1232) resonance in nuclei are studied by analyzing the quasifree decay reactions {sup 12}C({pi}{sup +},{pi}{sup +}p){sup 11}B and {sup 12}C({sup 3}He,t{pi}{sup +}p){sup 11}B and the 2p emission reactions {sup 12}C({pi}{sup +},pp){sup 10}B and {sup 12}C({sup 3}He,tpp){sup 10}B. The coincidence cross sections are calculated within the framework of the isobar-hole model. It is found that the 2p emission process induced by the decay of the {Delta} resonance in the nucleus can be consistently described by a {pi}+{rho}+g{sup {prime}} model for the {Delta}+N{r_arrow}N+N decay interaction. {copyright} {ital 1997} {ital The American Physical Society}
