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

英文摘要：

In \cite{Bodek:2020wbk} Bodek and Cai have tried to extract the potentials for nucleons and $Δ$ resonances from electron-nucleus inclusive scattering data. They find that the $Δ$ 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 ($γA$) interactions, performed about 35 years ago.
