| 摘 要： | Electronic states of CF2Cl2 （dichlorodifluoromethane, Freon 12） have been studied using a new type of electron momentum spectrometer with a very high efficiency at an impact energy of 1200 eV plus binding energy. The experimental electron momentum profiles are compared with the density functional theory （DFT） and Hartree-Fock （HF） calculations. The relationship between orbital assignments in different coordinate systems is discussed. A new method of difference analysis based on the new type of electron momentum spectrometer is used to clarify the ambiguities regarding the orbital ordering.

| Abstract: | Electronic states of CF$_{2}$Cl$_{2}$ (dichlorodifluoromethane, Freon 12)
have been studied using a new type of electron momentum spectrometer with a
very high efficiency at an impact energy of 1200 eV plus binding energy. The
experimental electron momentum profiles are compared with the density
functional theory (DFT) and Hartree--Fock (HF) calculations. The relationship
between orbital assignments in different coordinate systems is
discussed. A new method of difference analysis based on the new type of
electron momentum spectrometer is used to clarify the ambiguities
regarding the orbital ordering. |
