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 $\frac{\Delta p}{p}$ below the elastic peak and deduced the deuteron inelastic structure function $\nu W_2$. We found $\nu W_2\left({\omega }^{\prime }\right)$ approaching a universal scaling curve and a close relation between $\nu W_2$ and the deuteron elastic structure function $A\left(q^2\right)$.
