Neutral Meson Production with Polarized X Rays

Abstract

Measurements of ${\pi }^0$ photoproduction have been made at 235, 285, 335, and 435 MeV, using a beam of polarized x rays. Using a calculated value of polarization, an analysis is made which indicates a possible need for $\gamma$, $\rho$, $\pi$, or $\gamma$, $\omega$, $\pi$ coupling. The polarization calculations are checked by measurements made as a function of photon production angle at 335 MeV.
