Relativistic manybody calculations of [2p^{5}3s] excitedstate energy levels for neonlike ions
Abstract
Relativistic manybody perturbation theory is applied to determine energies of [2p^{5}3s] excited states of neonlike ions with nuclear charges in the range Z=1092. These calculations start with a V^{(N1)} HartreeFock potential and include correlation corrections. Corehole corrections are treated to all orders in perturbation theory while the corecore, valencecore, and valencehole corrections are treated to second order only. The Breit interaction is also included to second order, but the dominant correlation corrections to the Breit interaction are identified and iterated to all orders. Frequencydependent corrections to the Breit interaction and masspolarization corrections are treated to first order only. Lowestorder radiative corrections are included by evaluatng the electron selfenergy and vacuum polarization in a local potential that approximates the HartreeFock potential. Detailed comparisons are made with measurements and with other calculations.
