Negative Pion Production from Neutrons by Polarized gamma Rays

Nishikawa, T. ; Hiramatsu, S. ; Kimura, Y. ; et al.
Phys.Rev.Lett. 21 (1968) 1288-1291, 1968.

The differential asymmetry ratio for the process γ+n→p+π− was measured at 90° in the center-of-mass system and for incident photon energies from 352 to 550 MeV. The observed asymmetries are larger than the values predicted from the theory by Berends, Donnachie, and Weaver. A smaller M1- amplitude gives better agreement between the experiment and the theory.

Positive-Pion Production Asymmetry with Polarized Bremsstrahlung Near Second Resonance

Liu, F.F. ; Vitale, S. ;
Phys.Rev. 144 (1966) 1093-1100, 1966.
Inspire Record 50917 DOI 10.17182/hepdata.26643

The azimuthal asymmetry Σ=(σ⊥−σII)(σ⊥+σII) in π+ photoproduction by linearly polarized bremsstrahlung was measured at photon energies from 475 to 750 MeV at 90° and 135° in the center-of-mass system. The experimental results show that even in this energy region, π+ are produced predominantly in the plane of the magnetic vector.
