Isotope 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 کاملIsotope Shift in Mg I
The lines of the Mg I spectrum, lying in the visible and in the photographic infrared regions, have been examined and some of them found to show structure. It is pointed out that the structure should be attributed to isotope shift, which, in the case of the 3s3p 'P —3s3d 'D series, owes its origin to the fact-that the smd 'D terms, perturbed by the p''D term, have passed on to this term some of...
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.
