摘要：
Double-spin asymmetries in exclusive rho, Phi, and J/psi production in longitudinally polarised lepton-nucleon scattering have been measured at the HERMES experiment, using the 1996-1997 data on the polarised hydrogen target. The analysis is focused on the rho meson and a significant positive asymmetry A(1)(rho) was found. Much smaller Phi and J/psi data samples shaw asymmetries consistent With zero.
