Abstract

Abstract: Isobaric charge-exchange reactions induced by beams of 112 Sn have been investigated at the GSI facilities using the fragment separator FRS. The high-resolving power of this spectrometer makes it possible to obtain the isobaric charge-exchange cross sections with an accuracy of 3% and to separate quasi-elastic and inelastic contributions in the missing-energy spectra, in which the inelastic component is associated to the in-medium excitation of baryonic resonances such as the Δ resonance. We report on the results obtained for the (p, n) and ( n, p ) channels excited by using different targets that cover a large range in neutron excess.
