Abstract / Description of output
The circular photon asymmetry for pi(0)eta photoproduction on the proton was measured for the first time at the tagged photon facility of the MAMI C accelerator using the Crystal Ball/TAPS photon spectrometer. The experimental results are interpreted within a phenomenological isobar model that confirms the dominant role of the Delta(1700)D-33 resonance. The measured asymmetry allows us to identify small contributions from positive-parity resonances via interference terms with the dominant D-33 amplitude. (C) 2010 Elsevier B.V. All rights reserved.
