    "abstract": "We report first ab initio relativistic correlation calculations of potential\ncurves for ten low-lying electronic states, effective electric field on the\nelectron and hyperfine constants for the ^3\\Delta_1 state of cation of a heavy\ntransition metal fluoride, HfF^+, that is suggested to be used as the working\nstate in experiments to search for the electric dipole moment of the electron.\nIt is shown that HfF^+ has deeply bound ^1\\Sigma^+ ground state, its\ndissociation energy is D_e=6.4 eV. The ^3\\Delta_1 state is obtained to be the\nrelatively long-lived first excited state lying about 0.2 eV higher. The\ncalculated effective electric field E_eff=W_d|\\Omega| acting on an electron in\nthis state is 5.84*10^{24}Hz/(e*cm)",
