We present a review of experimental and theoretical studies of anomalous electronic properties observed to small metal particles. If the particle size is smaller than the electron mean free path in a volume, the electron-lattice energy exchange is strongly suppressed. This peculiarity, along with the possibility to feed high power densities into small particles, allows pronounced nonequilibrium heating of electrons and can cause specific electron and light emission from dispersed (island) metal films. The absorption of electromagnetic radiation by small metal particles is highly critical regarding their shape when the particle size is smaller than the wavelength and the radiation frequency is much lower than the plasma frequency.Comments: Refs. 22, Figs. 4, Tabs. 0.
