摘要：

The electron energy loss spectrum in the energy region of 42-48.5 eV of neon is measured with an angle-resolved fast-electron energy-loss spectrometer at an incident electron energy of 2500 eV. Besides the dipole-allowed au-toionization transitions of 2s-1 np (n = 3,4) and 2p-2 3s3p, the dipole-forhidden ones of 2s-1 ns (n = 3 - 6) and 2s -1 3d are observed. The line profile parameters, i.e. Er, F and q for these transitions, are determined, and the momentum transfer dependence behaviour is discussed. © 2008 Chinese Physical Society and IOP Publishing Ltd.
