WASA-at-COSY实验中，在2.14 GeV的质子束能量下进行的pd反应的光度是由前向pd弹性散射决定的，它产生的平均射束对靶值为[5.2±0.3（stat）±0.3（syst）] × 1030 s−1 cm−2。此外，在该束流能量下，当四动量转移平方t在0.16（GeV/c）~ 2和0.78（GeV/c）~ 2之间时，得到了前向pd弹性散射角分布，并与其它实验数据和pd双散射模型进行了比较。
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±0.3(stat)±0.3(syst)] × 1030 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.
