Form-independent third-order transition amplitudes for atoms with one valence electron
A procedure is given for calculating transition amplitudes that are equal in the length and velocity forms for transitions in atoms with one valence electron within the framework of relativistic many-body perturbation theory starting from the Dirac-Hartree-Fock approximation. This procedure is applied to obtain formindependent secondand third-order dipole matrix elements for the principal trans...
متن کاملPrecision calculations of atoms with few valence electrons
We discuss the possibility of using pair-equations for the construction of the effective Hamiltonian H eff for valence electrons of an atom. The low-energy part of atomic spectrum is found by solving the eigenvalue problem for H eff. In this way it is possible to account efficiently for the valence-valence and core-valence correlations. We tested this method on a toy model of a four-electron at...
متن کاملIsotope shift calculations in Ti II
We present an accurate ab initio method of calculating transition energies and isotope shifts in the 3d-transition metals. It extends previous work that combines the configuration-interaction calculation with many-body perturbation theory by including the effective three-body interaction and modification of the energy denominator. We show that these effects are of importance in Ti II. The need ...
متن کاملMany-Body Calculations of the Isotope Shift
Atomic energy levels are commonly evaluated assuming that the nuclear mass is infinite. In this report, we consider corrections to atomic levels associated with finite nuclear mass. These corrections are referred to as isotope shifts. We evaluate isotope shifts using many-body perturbation theory (MBPT), following the pioneering work by Mårtensson-Pendrill et al. [1, 2, 3, 4, 5, 6, 7, 8, 9]. We...
متن کاملris3: A program for relativistic isotope shift calculations
An atomic spectral line is characteristic of the element producing the spectrum. The line also depends on the isotope. The program ris3 (Relativistic Isotope Shift) calculates the electron density at the origin and the normal and specific mass shift parameters. Combining these electronic quantities with available nuclear data, isotope-dependent energy level shifts are determined.
