Abstract

The process

γ + p \to π^{+} + n

has been studied with 12-GeV linearly polarized photons for momentum transfer

t

from - 0.04 to - 1.0

{(G e V / c)}^{2}

. The experiment used a coherent bremsstrahlung beam produced by a diamond crystal. The measured asymmetry,

\frac{(d σ_{⊥} - d σ_{∥})}{(d σ_{⊥} + d σ_{∥})}

, is positive throughout this

t

range and is similar to measurements at lower energies.
