    "abstract": "This work is aimed at the multiconfigurational Hartree-Fock calculations of\nthe Er ionization energy. Authors have used the ATSP MCHF version in which\nthere are new codes for calculation of spin-angular parts written on the basis\nof the methodology Gaigalas, Rudzikas and Froese Fischer, based on the second\nquantization in coupled tensorial form, the angular momentum theory in 3 spaces\n(orbital, spin and quasispin) and graphical technique of spin-angular\nntegrations. They allow the study of configurations with open f-shells without\nany restrictions and lead to fairly accurate values of spectroscopic data.",
