Abstract
The crossed channels of generalized γN → γN reactions are considered. The coefficients in the transformation from independent helicity amplitudes to invariant functions are calculated. Explicit expressions for the invariant functions are derived with allowance for the contribution from the Born diagrams in the s, u, and t channels and the diagrams for six resonances in the s and u channels. It is shown that the calculated invariant functions satisfy the crossing-symmetry requirements.
