Quantum-mechanical model for valence-electron emission from metal surfaces

A quantum-mechanical (QM) model was used for investigating the emission probability of valence electrons at high impact energies. A precise representation of the electronic interactions was introduced within the binary collisinal formalism. The main features of the metal surface were described using...
