DeuteronA(q 2 ) structure function in the low and mediumq 2 range

The deuteronA(q ² ) structure function is calculated up toq ²=20 fm^–2 with the Paris potential including relativistic nucleonic and mesonic corrections. Different parametrizations (Iachello et al., Galster et al., Höhler et al., Gari and Krümpelmann (GK)) of the nucleon electromagnetic form factors (emff) are used. Unlike the data of Simon et al., those recently taken at Saclay are reasonably well reproduced by our full predictions for the first three emff considered. On the contrary, the predictions for the GK model fail to fit the Saclay data. The dependence ofA(q ² ) on the cut-off masses of the hadronic form factors is also investigated.
