- Abstract
- The G asymmetry of the gamma p -> N pi reaction has been measured for the first time for E gamma = 340 +/- 14 MeV. This observable, for which very scarce published data exist, plays an important role to disentangle the contributions of the various nucleon resonances. The experiment, performed at the Mainz microtron MAIM, used a 4 pi-detector system, a linearly polarized, tagged photon beam, and a longitudinally polarized proton target.
