    "abstract": "Recently obtained polarized target and photon asymmetry data in eta\nphotoproduction are shown to be very powerful, in conjunction with the\ndifferential cross-section data, in yielding model-insensitive constraints on\nthe electrostrong parameters for the excitation and decay of the $N^{*}(1520)$\nresonance. The extracted ratio of its electromagnetic helicity amplitudes,\n$A_{3/2}/A_{1/2}$, provides a critical test for the QCD-inspired hadron models.",
