Abstract :
Giving three examples, the form factors of the nucleon, the polarisability of the charged pion and the interference of the S 11 ( 1535 ) with the D 13 ( 1520 ) excitation of the nucleon in the η p -decay channel, it is argued that the hadron structure at low momentum transfer is highly significant for studying QCD.
