Spectral Functions and Nuclear Response
arXiv:0709.2536 · doi:10.1063/1.2834460
Abstract
I discuss the relation between the nuclear response and the Green function describing the propagation of a nucleon in the nuclear medium. Within this formalism, the widely used expressions in terms of spectral functions can be derived in a consistent and rigorous fashion. The results of recent applications to the study of the inclusive electron-nucleus cross section in the impulse approximation regime are brielfy analyzed.
