Electric-field effects on the doubly excited resonances of H^- below the H(N = 3) threshold are investigated theoretically using a method of complex-coordinate rotation. Products of Slater orbitals are used to represent the two-electron wave functions, with lmax = 5 employed for individual electron. Block matrices with up to Lmax = 6 (I-states) are used. Convergence behaviors for the resonance parameters (resonance energy and width) are examined by using different values of Lmax. Results for the electric-field effects on the M = 0 components of the Feshbach 1Se(1), 1P0(1), 1De(1), and‘'D”(1) resonances are given, as well as the effects on the M = ±1 components of the latter three states.
