摘要/Abstract

摘要： The valence-shell excitations of krypton atom have been investigated by fast electron impact with an angle-resolved electron-energy-loss spectrometer. The generalized oscillator strengths for some higher mixed valence-shell excitations in 4d, 4f, 5p, 5d, 6s, 6p, 7s $\leftarrow$ 4p of krypton atom have been determined. Their profiles are discussed, and the generalized oscillator strengths for the electric monopole and quadrupole excitations in $5\p \leftarrow 4\p$ are compared with the calculations of Amusia \it et al. (\it Phys. Rev. A \textbf67 022703 (2003)). The differences between the experimental results and theoretical calculations show that more studies are needed.
