Book Description
The Lecture series on Intermediate Structure in Nuclear Reactions was held in June 1966 at the University of Kentucky. Four lecturers had been invited to present series of three lectures each. Four lecturers had been invited to present series of three lectures each. Unfortunately, Dr. James E. Young was unable to attend the series. He did, however, submit a manuscript and we are fortunate to be able to have his approach represented in this volume. The three lecturers who did attend, Drs. R. H. Lemmer, L. Rodberg, and A. Lande, gave one lecture on each of the three days. The sessions were distributed through the day to allow ample time for discussion. The fact that the conference was small helped to stimulate exchanges between both lecturers and auditors. Some of the discussion sessions were nearly as long as the lectures which they followed.

Book Description
Kawai, Kerman, and McVoy have shown that a statistical treatment of many open channels that are coupled by direct reactions leads to modifications of the Hauser- Feshbach expression for energy-averaged cross section (Ann. of Phys. 75 (1973) 156). The energy averaging interval for this cross section is on the order of the width of single particle resonances, 1MeV, revealing only a gross structure in the cross section. When the energy-averaging interval is decreased down to a width of a doorway state 0.1 MeV, a so-called intermediate structure may be observed in cross sections. We extend the Kawai-Kerman-McVoy theory into the intermediate structure by leveraging a theory of doorway states developed by Feshbach, Kerman, and Lemmer (Ann. of Phys. 42 (1967) 230). As a byproduct of the extension, an alternative derivation of the central result of the Kawai-Kerman-McVoy theory is suggested. We quantify the effect of the approximations used in derivation by performing numerical computations for a large set of compound nuclear states.
