The Single-Particle Spectral Function of ${}^{16}\mathrm{O}$

Abstract

The influence of short-range correlations on the $p$-wave single-particle spectral function in ${}^{16}\mathrm{O}$ is studied as a function of energy. This influence, which is represented by the admixture of high-momentum components, is found to be small in the $p$-shell quasihole wave functions. It is therefore unlikely that studies of quasihole momentum distributions using the $(e,e^{\prime }p)$ reaction will reveal a significant contribution of high momentum components. Instead, high-momentum components become increasingly more dominant at higher excitation energy. The above observations are consistent with the energy distribution of high-momentum components in nuclear matter.
