| Abstract: | Nonlocal operator of potential is suggested, based on the “nearest neighbour” approximation (NNA) for single electron wave function in metals. It is shown that Schrödinger equation with nonlocal potential leads to quite simple analytical expression for work function, which surprisingly well fits to experimental data. |
| Keywords: | Work function Nonlocal potential The nearest neighbor approximation |
