摘要：

The angular-resolved energy-distribution functions for photoelectrons emitted from Si (111) cleavage planes are presented for plane-polarized light with photon energies below 7.1 eV at normal incidence. The spectra depend strongly on the direction of observation and on the direction of the polarization vector. A simple golden-rule expression for the number of emitted electrons is used to compare the experiments with a local-pseudopotential band-structure calculation. To interpret the results it is necessary to take into account the transition-matrix elements not only via the effect of selection rules, but by calculating them numerically. © 1979 The American Physical Society.
