Proportionality Relations in Charge-Exchange Reactions

Abstract

except for the forward spikes of the differential cross-sections of the so-called /;-exchange reactions. 3l In the Regge pole model the factorization relation of the differential sections is satisfied if the exchanges of only one Regge pole dominate the ential cross-sections, each of which is dominated by one helicity amplitude. it is well known that helicity non-flip amplitudes are inconsistent with the crossdiffer­ Ncnv, simple Regge pole model. Though helicity-flip amplitudes are consistent with the Regge pole model, they are also consistent with peripheral interaction models') and it is not clear i£ the factorization of the experimental differential cross-sections imli­ cates the factorization of underlying mechanism. In all cases where the relation (1) has been checked by experimental data the targets b and e are nucleons and the final baryons d and f arc the nucleon
