  The luminosity for a WASA-at-COSY experiment involving the pd reaction at
2.14 GeV proton-beam energy is determined by the forward pd elastic scattering,
which yields an average beam-on-target value of
[5.2\pm0.3(stat)\pm0.3(syst)]*10^{30} s^{-1}cm^{-2}. In addition, the forward
pd elastic-scattering angular distribution is obtained with four-momentum
transfer squared -t between 0.16 (GeV/c)^{2} and 0.78 (GeV/c)^{2} at this beam
energy, which is compared with other experimental data and the pd double
scattering model.
