摘要：

Using the results of the GRAAL Collaboration on the n photoproduction from the neutron target, we attempt to extract the partial radiative width of the possible new nucleon resonance N* (1675). The obtained estimates support this resonance to be a very attractive candidate for the non-strange member of the exotic antidecuplet of baryons - a partner of the theta(+) pentaquark. Our phenomenological value for the transition magnetic moment mu(n* n), appears to be in good agreement with the predictions of the Chiral Quark Soliton Model.
