| Abstract: | 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. |
