Abstract

A general analysis of polarization phenomena for coherent pion electroproduction on deuterons is presented. The spin and isospin structures of the gamma* + d --> d + P-0 amplitudes (where gamma* is a virtual photon) are established and relationships between meson electroproduction on deuterons and on nucleons are given in the framework of the impulse approximation. The reaction e + d --> e + d + pi(0) is investigated in detail, for a relatively large value of momentum transfer, 0.5 GeV2 less than or equal to -k(2) less than or equal to 2 GeV2, both at threshold and in the region of Delta-isobar excitation. Special attention is devoted to the sensitivity of different contributions to the exclusive cross section for d(e, epi(0))d, as the gamma*piomega form factor or the NN-potential. The predicted k(2)-dependence of the cross section agrees well with the available experimental data. (C) 2002 Elsevier Science (USA).
