Phys. Rev. A 71, 012503 (2005) [10 pages]Higher-order effective Hamiltonian for light atomic systemsReceived 29 September 2004; published 19 January 2005 We present the derivation of the effective higher-order Hamiltonian, which gives an mα6 contribution to the energy levels of an arbitrary light atom. The derivation is based on the Foldy-Wouthuysen transformation of the one-particle Dirac Hamiltonian followed by perturbative expansion of the many-particle Green function. The obtained results can be used for the high precision calculation of relativistic effects in atomic systems. © 2005 The American Physical Society URL:
