Abstract
Observation of a narrow structure at W ∼ 1.68 GeV in the excitation functions of some photon- and pion-induced reactions may signal a new narrow isospin-1/2 N(1685) resonance. New data on the γN → πηN reactions from GRAAL seems to reveal the signals of both N+(1685) and N0(1685) resonances.
