Photoproduction of [pi]^sup 0^[pi]^sup +^ pairs on proton and deuteron

The reaction of π0π+ photoproduction on free and quasi-free protons with γ-ray energies from 0.5 to 1.5 GeV has been studied. Its cross section was measured in the range [theta] π 0 [greater than or equal to] 20°. The distributions of π0π+, π0n, and π+n invariant masses were analyzed. The experiment...

Description
Summary:	The reaction of π0π+ photoproduction on free and quasi-free protons with γ-ray energies from 0.5 to 1.5 GeV has been studied. Its cross section was measured in the range [theta] π 0 [greater than or equal to] 20°. The distributions of π0π+, π0n, and π+n invariant masses were analyzed. The experiment was performed using the Compton back-scattered γ-ray beam at the GRAAL facility (Grenoble, France), applying liquid deuterium and hydrogen targets and a large-aperture (almost 4π) detector. Particular attention was paid to analysis of systematic errors related to the neutron detection efficiency.
