  We present a simplified method to generate the Hartree-Fock Gamow basis from
realistic nuclear forces. The Hartree-Fock iteration in the harmonic-oscillator
basis is first performed, and then the obtained HF potential is analytically
continued to the complex-k plane, finally by solving the Schr\"odinger equation
in the complex-k plane the Gamow basis is obtained. As examples, the method is
applied to 4He and 22O with the renormalized chiral N3LO potential. The basis
obtained which includes bound, resonant and scattering states can be further
used in many-body calculations to study weakly bound nuclei.
