摘要：
The newly introduced Transition Distribution Amplitudes (TDAs) are discussed for the pi-gamma transitions. Relations between pi-gamma and gamma-pi TDAs for different cases are given. Numerical values for the pi-gamma TDAs in different models are compared. GPD's feature's are extended to TDAs and the role of PCAC highlighted. We give hints for the evaluation of cross sections for meson pair production in our approach.
