Abstract
Many-body theory is developed to calculate the spectra for positron annihilation in noble-gas atoms. Inclusion of electron-positron correlation effects and core annihilation gives spectra in excellent agreement with experiment [K. Iwata et al., Phys. Rev. Lett. 79, 39 (1997)]. The calculated correlation enhancement factors for individual electron orbitals are found to scale with the ionization energy (in eV), as , where , , and .
