摘要：

The kinematic-singularity structure of helicity amplitudes for Compton scattering from arbitrary-spin hadron targets is obtained by an analysis based on the crossing relations. Explicit formulas are given for a complete set of amplitudes free of kinematic singularities and zeros in both variables. These amplitudes are, however, subject to constraint conditions at special points. The constraints are not studied here. © 1968 The American Physical Society.
