Abstract
Electroproduction of a ρ0 vector meson in the process γ* + 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 
are extracted from the data.
