The intercalation of Ne in C-60 Solids has been studied. Gas effusion spect
rum of C-60 powder exposed to Ne at 100 degrees C, three evolution peaks of
Ne are found near 100, 200 and 250 degrees C. Electrical resistivity of a
C-60 film increases by the exposure to Ne at 100 degrees C. Electron spin d
ensity of a C-60 film does not vary by the exposure to Ne. The intercalatio
n of Ne and its effect on electronic properties of C-60 solids are discusse
d.
