Evidence for a positive longitudinal double-spin asymmetry <A(l)(rho)> = 0.24 +/- 0.11(stat) +/- 0.02(syst) in the cross section for exclusive diffractive rho (0)(770) vector-meson production in polarised lepton-proton scattering was observed by the HERMES experiment. The longitudinally polarised 27.56 GeV HERA positron beam was scattered off a longitudinally polarised pure hydrogen gas target. The average invariant mass of the photon-proton system has a value of <W > = 4.9 GeV, while the average negative squared four-momentum of the virtual photon is <Q(2)> = 1.7 GeV2. The ratio of the present result to the corresponding spin asymmetry in inclusive deep-inelastic scattering is in agreement with an early theoretical prediction based on the generalised vector-meson dominance model.
