Description

Title:QED correction for H3+
Author(s):Polyansky, Oleg
Contributor(s):Zobov, Nikolay Fedorovich; Alijah, Alexander; Tennyson, Jonathan; Lodi, Lorenzo
Subject(s):Fundamental interest
Abstract:A quantum electrodynamics (QED) correction surface for the simplest polyatomic and polyelectronic system H$_3^+$ is computed using an approximate procedure. This surface is used to calculate the shifts to vibration-rotation energy levels due to QED; such shifts have a magnitude of up to 0.25~cm$^{-1}$ for vibrational levels up to 15~000~cm$^{-1}$ and are expected to have an accuracy of about 0.02~$^{-1}$. Combining the new H$_3^+$ QED correction surface with existing highly accurate Born-Oppenheimer (BO), relativistic and adiabatic components suggests that deviations of the resulting {\it ab initio} energy levels from observed ones are largely due to non-adiabatic effects.
