Abstract:

In our previous papers we have proposed the peripheral orbit model by introducing a peripheral Regge trajectory in the direct channel. The radius and absorptivity of the orbit are related to Re α and Im α, respectively. The width of the orbit is introduced through the factor e(J, s) (O[exp (-MJ/p)] as Re J →∞) and Im α.
In this article the model is applied to exotic reactions into which no peripheral Regge trajectory can be introduced. The exotic forward reaction amplitudes are defined from their u-channel reaction amplitudes through analytic continuation. The imaginary parts of the exotic reaction amplitudes are shown to have non-peripheral components due to the analytic continuation of the factor e(J, s).
The model is applied to π-p →π0n, π-p →ηn, K+n →K0p and K-p →K0n.
