摘　　要：报导了在高分辨率电子动量谱仪上获得的环戊烷分子的结合能谱和动量谱的实验结果，并用Ｈａｒｔｒｅｅ－Ｆｏｃｋ方法和密度泛函方法做了理论计算，实验得到的环戊烷分子各电子轨道的电离能值与光电子谱得到的数据一致，动量分布的实验结果也与理论计算基本吻合。The valence electron structure of cyclopentane was measured by using high resolution (Delta E = 1. 16 eV, Delta P = 0. 1 au) (e, 2e) spectrometer. The impact energy was 1200 eV plus binding energy ( i. e. 1206 to 1224 eV) and a symmetric non-coplannar kinematics was employed. The measured binding energies agree with the data obtained by photoelectron spectra (PES). The experimental momentum profiles have been compared with those calculated using the Hartree-Fock method and the density function theory (DFT) method. The measured momentum distributions are consistent with the theoretical calculations.
