Photoproduction of eta meson between threshold and 900 mev

Delcourt, B. ; Lefrancois, J. ; Perez-Y-Jorba, J.P. ; et al.

Phys.Lett.B 29 (1969) 75-78, 1969.

Inspire Record 56793 DOI 10.17182/hepdata.28963

We have measured differential cross sections of γ + p → p + η 0 at several energies. The angular distributions show that S 11 production is predominant in the energy range investigated and that the other resonant terms seen in π-production of η are absent or very low. Finally, experimental data are theoretically interpreted and the S 11 parameters deduced.

Differential cross-sections for the photoproduction of eta mesons from protons near 2 gev

Differential cross sections for the process γ p → p η have been measuredd at c.m. angles of 28°, 35° and 42° at incident energies between 2 GeV and 2.8 GeV. Data from an earlier experiment below 2 GeV have been re-analysed and corrected. The whole set of data is compared with the form ( s − M 2 ) 2 d σ /d t , which fits data at higher energies. There is good agreement above 2 GeV, particularly at the largest angle, but strong departures below.

Differential Cross Sections in Eta Photoproduction from 0.8 to 1.45 GeV

The cross section for the process γp→pη was studied from 0.8- to 1.45-GeV incident photon energy at center-of-mass angles from 50 to 90°. The data cover a range of energies well beyond previous measurements. The results will aid in the study of I=12 nucleon isobars.
