在入射电子能量为2500eV，散射角为0°，2 °，4 °和6°时，测量了锂原子内壳层激发的电子能量损失谱。观察到（1s2s2）2S和（1s2s3S）3s2S两个光禁戒跃迁。确定了Is（2s2p3P）2P0与1s（2s2p1P）2P0的广义振子强度比，它们与动量转移无关.
Electron energy loss spectra for the inner shell excitations of atomic lithium are measured at an incident electron energy of 2500eV and scattering angles of 0°, 2°, 4° and 6°. Two optically forbidden transitions of (ls2s2)2 S and (1s2s3S)3s2 S are observed. The generalized oscillator strength ratios for Is{2s2p3 P)2P0 to 1s(2s2p1P)2P0 were determined, and they are independent of the momentum transfer.
