ResumoThe deuteron magnetic structure function $B({q}^{2})$ is calculated in the one-photon exchange approximation using the recently described approach based on the Bethe-Salpeter equation. In this approach contributions to the deuteron electromagnetic form factors when the spectator or the struck nucleon is on-mass-shell appear with equal weight. Results obtained without any free parameters and without including any meson-exchange currents are in good agreement with the available data. Predictions are made for $B({q}^{2})$ up to ${q}^{2}=8$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$ and they show a minimum at ${q}^{2}\ensuremath{\simeq}2 or 2.5$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$ depending on the choice of the $\mathrm{NN}$ interaction. This is in sharp contrast with the exchange-current calculations which do not exhibit a minimum for any ${q}^{2}<~8$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$.NUCLEAR REACTIONS $^{2}\mathrm{H}$($e$,$e$), ${q}^{2}<~8$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$, calculated $B({q}^{2})$, compared with experimental data.
