摘要：

It is shown that the simplest two-body pion rescattering model for pion absorption in nuclei leads to a rapid increase with pion energy for the absorptive part of the S-wave pion-nucleus optical potential proportional to p2. The energy dependence is almost entirely due to the pion-nucleon rescattering amplitude and not to nuclear structure effects.
