The total cross section for the {gamma}n{r_arrow}p{pi}{sup {minus}}{pi}{sup 0} reaction has been measured over the photon energy range 450{endash}800 MeV at the 855 MeV MAMI Microtron in Mainz with the large acceptance detector DAPHNE and using a deuterium target. As expected, this reaction has a very similar cross section to the {gamma}p{r_arrow}n{pi}{sup +}{pi}{sup 0} channel and its amplitude is strongly underestimated by the existing double pion photoproduction models. {copyright} {ital 1997} {ital The American Physical Society}
