Abstract

The Feshbach projection-operator technique is investigated using second quantization to construct approximate optical potentials with Tamm-Dancoff-approximation and random-phase-approximation descriptions for closed-shell targets. We interpret a recent many-body theory of elastic scattering (due to Schneider, Taylor, and Yaris) as an approximate form of the equations of this work. Possible applications and extensions of the method are also described.
