    "abstract": "We have calculated energy levels and lifetimes of 4f7 and 4f6 5d\nconfigurations of Gd IV using Hartree-Fock and configuration interaction\nmethods. This allows us to reduce significantly the uncertainty of the\ntheoretical determination of the electron electric dipole moment (EDM)\nenhancement factor in this ion and, correspondingly, in gadolinium-containing\ngarnets for which such measurements were recently proposed. Our new value for\nthe EDM enhancement factor of Gd+3 is -2.2 +- 0.5. Calculations of energy\nlevels and lifetimes for Eu~III are used to control the accuracy.",
