Long-Range Interactions for Hydrogen: 6P–1S and 6P–2S Systems
Long-Range Interactions for Hydrogen: 6P–1S and 6P–2S Systems
The collisional shift of a transition constitutes an important systematic effect in high-precision spectroscopy. Accurate values for van der Waalsinteraction coefficients are required in order to evaluate the distance-dependent frequency shift. We here consider the interaction of excited hydrogen 6P atoms with metastable atoms (in the 2S state), in order …
