consisting of the subshell L1 (one 1s electron) for Li.
Second, the average value of the 1s electron momentum is [p.sub.e] = [p.sub.1] and the average change in the electron momentum after ejection, [DELTA][p.sub.e], is such that [DELTA][p.sup.2.sub.e] = 2[m.sub.e]T, which is analogous to the free-electron case.
All obtained spectra were calibrated to a C 1s electron peak at 285.1 eV.
Thus, its threshold is at the binding energy of a single 1s electron in a neutral Cu atom.
In contrast, the energy of HOS has changed to that which is between -8.0 eV and 0.5 eV after adsorption, which is mainly caused by H 1s electron, O 2p electrons, and Fe 3d electrons.
Binding energies of photoelectrons were determined based on the assumption that carbon 1s electrons were at 284.5 eV.
