摘要
The gammap --> gammaetap reaction in the S-11(1535) resonance region is investigated as a method to access the S-11 (1535) magnetic dipole moment. To study the feasibility, we perform calculations of the gammap --> gammaetap process within an effective Lagrangian approach containing both the S-11 resonant mechanism and a background of non-resonant contributions. Predictions are made for the forthcoming experiments. In particular, we focus on the sensitivity of cross sections and photon asymmetries to the S-11 (1535) magnetic dipole moment.
