Eta photoproduction

We present a combined analysis of the new eta photoproduction data for total and differential cross sections, target asymmetry and photon asymmetry. Using basic assumptions, this allows a model-independent extraction of the $E_{2-}$ and $M_{2-}$ multipoles as well as resonance parameters of the $D_{13}(1520)$ state. At higher energy, we show that the photon asymmetry is extremely sensitive to small multipoles that are excited by photons in the helicity 3/2 state. These could be, e.g., the $F_{15}(1680)$, the $F_{17}(1990)$, or the $G_{17}(2190)$ resonances.Comment: 9 pages LATEX including 5 Figurs, Proc. of the GW/TJNAF Workshop on N* Physics, 1997, to be published in pi-N Newsletter

The Anomalous Decay eta -> pi pi gamma gamma

We investigate the rare radiative eta decay modes eta -> pi+ pi- gamma gamma and eta -> pi0 pi0 gamma gamma within the framework of chiral lagrangians at o(p^4) and present photon spectra for both processes.Comment: 5 pages, revtex preprint, PS figures in separate file, presented at the International School of Nuclear Physics, Erice, Sicily, Italy, September 199
