Long-Range Interactions for Hydrogen: 6P-1S and 6P-2S
U. D. Jentschura, C. M. Adhikari
The collisional shift of a transition constitutes an important systematic effect in high-precision spectroscopy. Accurate values for van der Waalsinteraction coefficients are requi…
Long-range interactions of hydrogen atoms in excited states. III. nS-1S interactions for n >= 3
C. M. Adhikari, V. Debierre, U. D. Jentschura
The long-range interaction of excited neutral atoms has a number of interesting and surprising properties, such as the prevalence of long-range, oscillatory tails, and the emergenc…
Long-range interactions of hydrogen atoms in excited states. II. Hyperfine-resolved 2S-2S system
U. D. Jentschura, V. Debierre, C. M. Adhikari +2
The interaction of two excited hydrogen atoms in metastable states constitutes a theoretically interesting problem because of the quasi-degenerate 2P_{1/2} levels which are removed…
Long-range interactions of hydrogen atoms in excited states. I. 2S-1S interactions and Dirac-delta perturbations
C. M. Adhikari, V. Debierre, A. Matveev +2
The theory of the long-range interaction of metastable excited atomic states with ground-state atoms is analyzed. We show that the long-range interaction is essentially modified wh…
