The stability of a charged metallic particle is investigated within the classical theory. The minimal number of atoms for which a charged spherical particle is stable against the spheroidal deformation, which relaxes the energy cost due to the Coulomb repulsion between extra charges, is derived. It is suggested that, for negatively charged particles, an extra electron virtually bound to particle is emitted before the fragmentation due to the Coulomb repulsion between extra charges will occur. |
