Розклад двочастинкового рівняння Дірака за степенями 1/с до вищих порядків
Using an extension of the Foldy–Wouthuysen transformation to two-particle wave equations, we consider the problem of expansion of the two-body Dirac Hamiltonian in powers of 1/c up to the fourth order. The transformed Hamiltonian in an even-even form toorder 1/c4 is obtained. It is shown that the ex...
