Among the lattice of C-60 in Na3HC60, the three component molecular superconductor, the hydride ions, H-delta, are expected to form a conduction band. In C60X(X=He, Ar, Kr), it could be inferred that some bonding state exists between C60 and rare gases intercalated C60 lattice. These works may suggests that a unique banding field is generated in the molecular spaces. These studies of various phenomena in these field will, be able to develop the new science. We would like to name the research filed as "Hidden Surface Science".
