Article	S. Kröger, M. Kröger A program to compute the angular coefficients of the relativistic one-electron hyperfine structure parameters Comput. Phys. Commun. 90 (1995) 381-387
The Chfs program calculates the angular coefficients alpha_{nl}^{k_sk_l} and beta_{nl}^{k_sk_l} of the relativistic one-electron hyperfine structure parameters for the case of pure SL-coupling or, alternatively, the case of intermediate coupling. The calculation is based on SL-basis states and, optionally, mixing coefficients of the electronic wave functions of atoms. The derivation of the necessary matrix elements is based on the effective tensor operator formalism; explicit expressions are cited. Chfs is the first program which is able to compute the angular coefficients for electronic configurations with up to four electron shells. for LaTeX users @article{SKroger1995-90,  author = {S.
