THE SPIN-ISOSPIN RESPONSE

Three aspects of the response in the spin-isospin channel is discussed , Inclusive data with charge exchange reactions show significant cross sections in the spin-transverse channel beyond contributions from a 1 p-1h model space. Similar effects are seen in electron scattering. One -proton emission spectra have been obtained to show missing momentum d istributions in the quasielastic and dip region, Evidence for coherent pions in charge exchange are presented and discussed in terms of scat tering of virtual pions.
