Among the lattice of C-60 in Na3HC60, the three component molecular superco
nductor, 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 sugge
sts 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 n
ew science. We would like to name the research filed as "Hidden Surface Sci
ence".
