Abstract
The first experimental results for the coherent pi(0) electroproduction on a deuteron, e + d --> e + d + pi(0), at large momentum transfer, are reported. The experiment was performed at Jefferson Laboratory at an incident electron energy of 4.05 GeV. A large pion production yield has been observed in the kinematical region 1.1 < Q(2) < 1.8 GeV2, from the threshold to 200-MeV excitation energy in the dpi(0) system. The Q(2) dependence is compared with theoretical predictions. (C) 2003 MAIK "Nauka/Interperiodica".
