Pion reabsorption in heavy-ion collisions interpreted in terms of the #DELTA# capture process

We have measured energy-differential cross sections for #pi#"0 production in "3"6Ar+"1"9"7Au collisions at 95 MeV/u. From an analysis of spectral features due to pion final-state interactions we have estimated the cross section of the capture process #DELTA#+N#->#N+N in the center-of-mass energy range #sq root#s#approx =#2.05-2.25 GeV. Within the frame of BUU calculations, our results support the extension of the detailed-balance principle to broad-width resonances.
