Inclusive pion double charge exchange on {sup 16}O above the {delta} resonance

The forward inclusive pion double charge exchange reaction, {sup 16}O({pi}{sup -},{pi}{sup +})X, at T{sub 0}=0.50 and 0.75 GeV has been studied in the kinematic region where an additional pion production is forbidden by energy-momentum conservation. The experiment was performed with the SKS spectrom...

Description
Summary:The forward inclusive pion double charge exchange reaction, {sup 16}O({pi}{sup -},{pi}{sup +})X, at T{sub 0}=0.50 and 0.75 GeV has been studied in the kinematic region where an additional pion production is forbidden by energy-momentum conservation. The experiment was performed with the SKS spectrometer at KEK PS. The measured ratio of double charge exchange cross-section for these energies /=1.7{+-}0.2, disagrees with the value of 7.2 predicted within the conventional sequential single charge exchange mechanism. Possible reasons for the disagreement are discussed in connection with the Glauber inelastic rescatterings.
