Electron-Deuteron Scattering in the Inelastic Threshold Region at High Momentum Transfer

Abstract

At squared momentum transfers $0.8<~{q}^{2}<~6.0$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$, we measured nine spectra of inelastic electron-deuteron scattering cross sections in the threshold region between 0 and 2.3% in $\frac{\ensuremath{\Delta}p}{p}$ below the elastic peak and deduced the deuteron inelastic structure function $\ensuremath{\nu}{W}_{2}$. We found $\ensuremath{\nu}{W}_{2}({\ensuremath{\omega}}^{\ensuremath{'}})$ approaching a universal scaling curve and a close relation between $\ensuremath{\nu}{W}_{2}$ and the deuteron elastic structure function $A({q}^{2})$.
