 note = {In this research, electronic structure of the hollandide-type titanium oxides Ba1.06Ti8O16 made during the N2 gas and the hollandide-type titanium oxides Ba1.58Ti8O9.38 made during the atmosphere were investigated by means of X-ray and Ultraviolet-ray photoelectron spectroscopy. Ba1.06Ti8O16 in a UPS spectrum near Fermi level by 310 K and 190 K, has been formed metal-insulator transition because a gap opens. A UPS spectrum near Fermi level of metallic phase exhibits a power-law dependence on the electron binding energy, indicating that conduction electrons in Ba1.06Ti8O16 behave as a Luttinger liquid. In addition, a Ti atom is mixed valence state the metallic phase and the insulator look from a XPS spectrum, but its ratio is changing before and after. On the other hand, Ba1.58Ti8O9.38, in a UPS spectrum near Fermi level by 310 K, is the insulator because a gap open, and in a XPS spectrum by 310 K, is not mixed valence state in a Ti atom.},
