Аннотация:The results of a partial-wave analysis of the angular distributions for the process gammap --> etap over the energy range up to 2 GeV are presented. Reliable estimates of the Breit-Wigner parameters of the S-11 (1535) resonance, as well as the energy dependence of the real and imaginary parts of the electric dipole amplitude E0+ and its phase, are derived from the energy dependence of the regression coefficient a(0)(W).
