The $p p \\to n X$ reaction is used to fix the $pn\\pi^+$ form factor for three different models. We take into account the possible destruction of the residual neutron by the projectile. Using the form factor from the hadronic reaction we calculate photoproduction and small $x_{Bj}$ electroproduction of forward neutrons at HERA. Here the $q \\bar q$ dipoles in the photon can rescatter on the residual neutron. In photoproduction we observe slightly less absorption than in","authors_text":"H.J. Pirner, U.
