Abstract
The total cross section for the gamma n-->p pi(-)pi(0) reaction has be en measured over the photon energy range 450-800 MeV at the 855 MeV MA MI Microtron in Mainz with the large acceptance detector DAPHNE and us ing a deuterium target. As expected, this reaction has a very similar cross section to the gamma p-->n pi(+)pi(0) channel and its amplitude is strongly underestimated by the existing double pion photoproduction models.
