Dispersion approach to the inverse scattering problem

Dispersion relations for the np-system wave functions in sup(1)Ssub((0)sup(-)) sup(3)Ssub((1)sup(-)) and sup(3)Dsub(1) states have been derived. Using the relations the expressions for wave functions providing an approximate solution of the inverse scattering problem have been obtained. The dispersion relations are transformed into a set of singular integral equations; an obvious solution of this set is obtained. It is shown that the condition of normalization of the np-system wave functions in the state of scattering can be applied for determining the contribution of dynamic cuts
