Small, highly charged sodium clusters have been produced by multi-step ionization of large clusters followed by evaporative shrinking. The critical size, nc, beyond which Na~ + are stable obeys the approximate relation he= 8z 2. However, significant deviations from constant z2/nΒ’ are dearly evident.
Under generalized gradient approximation (GGA), geometrical structure, size dependence of stability and electronic properties of neutral Mg n , singly charged cationic Mg n + and singly charged anionic Mg n Γ clusters consisting of up to 11 atoms have been studied systematically by ab initio method
New very precise KLOE data on e + e -β Ο + Ο -obtained by radiative return method in Frascati are unified with corrected CMD-2 and SND Novosibirsk e + e -β Ο + Ο -data and supplemented below and beyond by older data in order to be described by the unitary and analytic pion electromagnetic form facto
## Multiphoton ionization of warm sodium chloride clusters generates "magic numbers" which are different from the anomalies reported after electron ionization or sputtering. They can be explained by assuming the desorption of all sodium halide admolecules outside rectangular neutral cluster cores
