Description

High-resolution laser-based measurements of energy levels have spurred the development and refinement of quantum electrodynamic calculations. We have extended very-high-resolution laser spectroscopy techniques into the vacuum ultraviolet wavelength region at λ ≈ 120 nm to determine the Lamb shift in the ground state of He I. The importance of this measurement to high accuracy quantum electrodynamics calculations is discussed. Details of the present measurement and future improvements are...[Show more]
