A model of a mixed helium-hydrogenic atmosphere of the isolated neutron star 1E1207.4-5209 is proposed. It is based on the assumption that the main components in the atmosphere are the exotic molecular ions He23+ and H32+ with the presence of He+, (HeH)2+, H2+ under a surface magnetic field ≈ 4.4 × 1013 G. In addition to two absorption features observed by \it Chandra observatory (Sanwal et al, 2002) the model predicts one more narrow absorption feature at ≈ 400 eV.
