摘要：
The Foldy-Wouthuysen Hamiltonian of a light atomic system that has an m alpha(8) contribution to energy levels is calculated. The case of a Dirac Coulomb field is discussed. The results can be used for relativistic and radiative corrections to energy levels in the low-energy part. A divergent operator delta(2)(r) emerges. This is probably due to the nature of the point-like charge source. The effective method of radiation calculation may be re-checked.
