Comment on "Comparison of optical potential for nucleons and $\Delta$ resonances" by Arie Bodek and Tejin Cai

Abstract

In \cite{Bodek:2020wbk} Bodek and Cai have tried to extract the potentials for nucleons and $\Delta$ resonances from electron-nucleus inclusive scattering data. They find that the $\Delta$ potential is considerably more attractive than that of the nucleons. This result is at variance with the results of a multitude of analyses of (e,A) and ($\gamma A$) interactions, performed about 35 years ago.
