Diffractive leptoproduction of {rho}0 mesons, {mu} + N {yields} {mu} + N + {rho} is measured at COMPASS at < W > = 10 GeV over a wide range of Q2, 0.01 < Q2 < 10 GeV2. Angular distributions allow to determine spin density matrix elements. Preliminary results from COMPASS 2002 data are presented. They are consistent with a substantial increase of R = {sigma}L/{sigma}T with Q2 and a weak violation of SCHC, in agreement with other high energy experiments.
