Abstract
The damping mechanisms of the Delta(1232) resonance in nuclei are stud ied by analyzing the quasifree decay reactions C-12(pi(+),pi(+)p)B-11 and C-12(He-3,t pi(+)p)B-11 and the 2p emission reactions C-12(pi(+),p p)B-10 and C-12(He-3,tpp)B-10. The coincidence cross sections are calc ulated within the framework of the isobar-hole model. It is found that the 2p emission process induced by the decay of the Delta resonance i n the nucleus can be consistently described by a pi+rho+g' model for t he Delta+N-->N+N decay interaction.
