摘要：
Electroproduction of a rho(0) vector meson in the process gamma* + N -> V + N' is measured with a 27.6 GeV longitudinally polarized electron/positron beam in the HERMES experiment. Kinematical dependences of real and imaginary parts of the ratio of the helicity amplitudes T-11/T-00(gamma(T)* -> rho(T))/(gamma(L)* -> rho(L)) are extracted from the data.
