The irradiation effects of C60 films induced by 0.98GeV Fe ions at the same electronic energy loss of 3.5keV/nm and different irradiation dose ranging from 5×10^10 to 8×10^13 ions/cm^2,were analyzed by Raman scattering and Fourier transform infrared spectroscopes.

利用傅立叶转换红外光谱和Raman谱仪分析了0.98 GeV的Fe离子在电子能损S为3.5keV/nm时，不同辐照剂量(5×10^10-8×10^13 ions/平方公分)下，在C60薄膜中引起的辐照损伤效应。

The electronic structures of cluster Fe8 with D6h symmetry and Fe15 with Oh sysmmetry have been studied by MS-X method..The results show that(1 the exchange splittings of the d-band and the magnetic moments of the Fe-atoms are different in the two clusters;(2)the change distribution in both clusters is not uniform,showing that the electrons are transferred from peripheral atoms to inner atoms,and the spin-directionof the electrons transferred is in accordance with the symmetric characteristics...
