Calculation of Fine Structure Parameters by Semiempirical Method from Energy Intervals between Magnetic Sublevels

摘要

A method is developed for the semiempirical calculation of fine structure parameters from the experimental energy intervals between magnetic sublevels. The calculations are performed using the 2p~(2) configuration of neutral carbon as an example. The calculated parameters are used to calculate the configuration energy spectrum and the gyromagnetic ratios of the ~(3)P_(2) and ~(1)D_(2) levels, as well as the magnetic splitting of triplet levels. The results are compared with available experimental and theoretical data. It is confirmed that the dependence of the energy of magnetic sublevels of np~(2) configurations on the magnetic induction is parabolic for sublevels with the projections M velence 0, +-1 and is linear for sublevels with M velence +-2.
