The strength of the -nucleus potential is calculated from the many-body Hamiltonian for , , and constructed by Betz and Lee. The results are compared to the empirical values of the -hole doorway model. It is found that the calculated strength of the central potential reproduces the empirical one to a large extent. However, the calculated spin-orbit potential is much smaller than that of of the -hole model. It is also shown that the pion absorption through the wave only accounts for about half of the total absorption. The sums of other partial waves are found to be equally important.
