Executive Summary
We will develop a predictive theory for inelastic nuclear scattering and use this new capability to determine an important nuclear reaction cross section that elucidates the origin of the elements. Our theory will enable reaction measurements for a wide range of radioisotopes currently not available, and lead to more reliable data evaluations for applications in nuclear energy, nonproliferation, and stockpile stewardship.
