    "abstract": "We describe a unified approach for the determination of ac-Stark correction\nand Kramers-Heisenberg dispersion formula. In both cases the contribution from\ninfinite intermediate summation appearing in the expression for the\ncorresponding matrix elements are evaluated exactly in the dipole approximation\nfor the ground state of hydrogen atom using a variation of the Dalgarno-Lewis\nmethod. The analytical expressions obtained can be efficiently used for the\nnumerical evaluation of matrix element for all values of incident photon energy\nand comparison is made with results obtained by different methods.",
