PHOTOPRODUCTION OF eta0 MESONS AT 4-Gev

Bellenger, D. ; Deutsch, S. ; Luckey, David ; et al.
Phys.Rev.Lett. 21 (1968) 1205, 1968.
Inspire Record 53018 DOI 10.17182/hepdata.21703

We have measured η0 photoproduction at 4 GeV. We find our results to be consistent with a theoretical preduction relating this cross section to ω0 production by π mesons using a vector-dominance model; there is no evidence for a dip or change of slope at −t=0.6 as seen in π0 photoproduction.

Differential Cross Sections in Eta Photoproduction from 0.8 to 1.45 GeV

Bloom, E.D. ; Heusch, C.A. ; Prescott, C.Y. ; et al.
Phys.Rev.Lett. 21 (1968) 1100-1103, 1968.
Inspire Record 54471 DOI 10.17182/hepdata.21721

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.

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.

RECOIL PROTON POLARIZATION IN ETA PHOTOPRODUCTION

Heusch, C.A. ; Prescott, C.Y. ; Rochester, L.S. ; et al.
Phys.Rev.Lett. 25 (1970) 1381, 1970.
Inspire Record 61494 DOI 10.17182/hepdata.21581

We measured the polarization of the recoil proton in the process γp→pη0, at 90° in the center-of-mass system, at incoming photon energies from 0.8 to 1.1 GeV. Detection of all three particles in the final state pγγ permitted observation of this process with little background. Subsequent rescattering off carbon nuclei yielded sizable polarization values for the protons, indicating considerable S−P—wave interference in the production process.
