Abstract
A useful way to characterize the hole-energy spectrum excited in a direct particle-removal reaction like () or () is through the centroid or mean removal energy. We derive the rules for computing this quantity in a linked-cluster expansion, and give some examples. We demonstrate the close relation of the mean removal energy to Brandow's self-consistent orbital energy, and discuss briefly the connection with Green's function theory.
