Comment on "Nucleus-nucleus total reaction cross sections"

In a recent article by DeVries and Peng, it was suggested that the concept of a geometric reaction cross section was not meaningful since ${\sigma }_R$ exceeded the geometric values for heavy nuclear charge distributions, in place of the required nuclear single-particle distributions, in the calculations for ${\sigma }_R$. Hence, the applicability of geometric limits for ${\sigma }_R$ remains undetermined.
