Abstract
Exclusive production of mesons on hydrogen and deuterium targets is studied in the HERMES kinematic region GeV and GeV. Spin density matrix elements and their and dependences are presented. These data are consistent with s-channel helicity conservation in exclusive meson production. No significant evidence for the contribution of unnatural-parity-exchange amplitudes is found.
