Abstract
We have investigated the -meson production mechanism in the three reactions and at 3.9 GeV/c ( ) using the prism-plot technique. Differential cross sections at all momentum transfers are presented. A significant backward peak has been found in all three reactions. The differential cross sections for these backward peaks are given and are compared with the equivalent pion elastic and charge-exchange cross sections in the backward direction. Using a linear combination of the three differential cross sections we have isolated the exchange contribution in the forward direction. This differential cross section has a zero at and is fitted by the dual absorptive model of Harari with an interaction radius of ∼ 1.2 F. The total cross section is calculated and compared with similarly determined cross sections at higher momenta. An analysis of the properties of the other possible spin-parity exchanges is also presented.
