✦ Synopsis

Off-forward structure functions of the pion are investigated in twist-two and twist-three approximation. A simple model is used for the pion, which allows to introduce finite size effects, while preserving gauge invariance. Results for the imaginary parts of the 7"7r --+ 7"7r off-forwaxd amplitude and of the structure functions are presented. Generalized Callan-Gross relations are obtained.
