Goals

By conducting systematic large-scale relativistic studies of a portion of the spectra including the ground state, the MCDHF/MCHF Collection aims at creating accurate ab initio collection of atomic transition data of the light atoms A detailed agreement between ab initio methods for computing atomic spectroscopic data and experiment requires the relativistic effects to be included even in light atoms. In addition, fine structure levels, inter-combination lines, and lifetimes of some levels can be accurately determined only by considering the relativistic effects (spin-orbit, spin-spin, and spin-other-orbit) and all computed data have included them.
