Abstract
The polarized vector-meson production in semi-inclusive
electron-nucleon scattering with longitudinally-polarized
electron beam has been investigated. The Drell-Yan like
representation for the spin-density matrix elements of the vector
meson, that takes into account the leading radiative corrections,
is derived. The calculations have been performed for two widely
used reference systems: the Gottfried-Jackson and the helicity ones.
