Contribution of the individual discrete levels to the Lamb shift in hydrogen atoms
B Blaive, A. O. Barut, R. Boudet
The authors have evaluated explicitly the transition form factors T mu mn (k), or the Fourier components of the transition currents, between states m and n, and with them, the contribution of an individual level m to the Lamb shift of level n, including the retardation exponentials.
