Investigation of the conjectured nucleon deformation at low momentum transfer.

The conjectured deviation of hadron shapes fromsphericity [1] is the subject of numerous experimen-tal [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12] and theoretical[13, 14, 15, 16, 17, 18, 19, 20] investigations. The sig-nature of the deformation of the nucleon is most oftensought through the isolation of resonant quadrupole am-plitudes in the γ
