Variational calculations using Hylleraas coordinates have been performed for the first time for estimating the energies of 3dnf({sup 1,3}D{sup o}) state of helium for n=4,5,6. We predict absorption peaks at 12.219, 12.647, and 12.857 eV for the {sup 3}D{sup o} series converging to N=3 ionization threshold of He{sup +} which can be expected to be observed in the experiment of single photon double excitation of lowest {sup 3}P{sup e} state of helium placed in synchrotron radiation.
