摘要：

Differential cross sections and generalized oscillator strengths have been measured for two optically allowed transitions 2p6(1S0)-->2p5(2P1/2,3/2)3s and the optically forbidden transition 2p6(1S0)-->2p5(2P1/2)3p in Ne. These measurements are carried out for electron kinetic energies 300, 400, and 500 eV at small scattering angles (theta=2.4-degrees-33.7-degrees) by means of electron-energy-loss spectroscopy. Optical oscillator strengths have been determined by extrapolating the generalized oscillator strengths to zero momentum transfer, as (0.137 +/- 0.018) and (0.0106 +/-0.0014), for the 2p5(2P1/2)3s and 2p5(2P3/2)3s states, respectively. Integrated cross sections have been calculated by integrating the differential cross sections for each impact energy. The errrors are estimated to be less than 13%.
