Experimental Results on Charge Exchange Reactions with {Delta} Excitations and Polarization Studies of {Delta} and N{sup *} (1440) Resonances

Abstract

Main results of inclusive and exclusive experimental studies of ({sup 3}He, t), (t, {sup 3}He), (p, n), (p, p`) reactions on protons and nuclei with {Delta} excitation are discussed and summarized. New possibilities for investigation of coherent pion production are discussed. We point out that experiments at various energies with different projectiles offer a possibility to separate partial contributions of mechanisms of charge-exchange reactions with excitation of broad baryonic resonances ({Delta} and N{sup *} (1440)) in nuclei. The importance of interference effects in this class of reactions is stressed. We discuss the (d, d`) reaction on protons and nuclei, which gives a possibility to study polarization effects in reactions with resonance excitations. Such information in the {Delta}, Roper and overlapping region, where interference between these resonances might be essential, can help much in understanding their properties and underlying mechanisms of the reactions considered. It is particularly important for the theory of charge-exchange reactions at intermediate energies which cannot at present provide quantitative description of these reactions with nuclei.
