Polarization of Recoil Protons from Neutral Pion Photoproduction

Lundquist, D.E. ; Anderson, R.L. ; Allaby, J.V. ; et al.
Phys.Rev. 168 (1968) 1527-1533, 1968.
Inspire Record 54507 DOI 10.17182/hepdata.26510

The polarization of recoiling protons from the photoproduction of π0 mesons on liquid hydrogen has been measured for primary photon energies between 500 and 1000 MeV over a range of π0 c.m. angles from 55° to 130°. The results show structure not observed previously in experiments of less precision. In particular, the polarization at 90° c.m. is close to zero at a primary photon energy of 900 MeV. Also, a strong dependence of polarization on π0 c.m. angle between 600 and 900 MeV was observed. A subsidiary measurement of the polarization of the recoil protons from elastic e−p scattering at 900 MeV and q2=10 F−2 gave a value (1.3±2.0)%.

A study of π − + p →η + n near threshold shows that the cross section rises linearly with η momentum and that Λ η < 0.9 MeV c 2 (95% confidence limit).
