“…Näher et al [24] determined experimentally critical numbers N = 64, 123, and 208 for clusters with n = 3, 4, and 5, respectively. In our model, we have N ≡ N i + ∆N * i , and n ≡ ∆N * i .…”

“…Unexpectedly, the examination of function ε F (α) indicates the insufficiency of its approximation by the expression (24). This expression is stair-like function, i.e., it is constant within intervals (α i+1 , α i ), where i F = i.…”

“…It can be explained by the fact that α i+1 and α i differ in the second order of smallness, and after substituting into (24) they give the same results (of course, terms of the order more than first must be omitted in the resultant expression). A numerical calculation of ε F by the formula (24) leads to the error that is associated with an incorrect consideration for terms of the order more than first and gives an appearance of the oscillatory dependence ε F (l).…”

Energetics of metal slabs and clusters: The rectangular-box model

An expansion of energy characteristics of wide thin slab of thickness L in power of 1/L is constructed using the free-electron approximation and the model of a potential well of finite depth. Accuracy of results in each order of the expansion is analyzed. Size dependences of the work function and electronic elastic force for Au and Na slabs are calculated. It is concluded that the work function of low-dimensional metal structure is always smaller that of semi-infinite metal sample.A mechanism for the Coulomb instability of charged metal clusters, different from Rayleigh's one, is discussed. The two-component model of a metallic cluster yields the different critical sizes depending on a kind of charging particles (electrons or ions). For the cuboid clusters, the electronic spectrum quantization is taken into account. The calculated critical sizes of Ag 2− N and Au 3− N clusters are in a good agreement with experimental data. A qualitative explanation is suggested for the Coulomb explosion of positively charged Na n+ N clusters at 3≤ n ≤5.

“…We introduce two methods: the first is based on photoionization, and the second is realized by the attachment of a highly charged ion such as O 5+ and Ar 8+ to a neutral particle. Näher et al have succeed to generate highly charged sodium clusters Na z+ n with 2 ≤ z ≤ 14 by using two different lasers [16]. In this method, Na clusters is transported by a cold helium gas stream into a high vacuum chamber and is photoionized with a dye laser pulse at a wavelength of 400 nm.…”

We study theoretically the trapping of a nanoparticle by a rotational motion around another nanoparticle caused by surface forces comprising electrostatic and Casimir forces. We introduce a local power exponent of the surface force as a function of the separation distance and show that it strongly depends on the electric charges carried by the nanoparticles. The stability of circular motions depends mainly on the local power exponent, and if the electric charges are not zero and the mass of the nanoparticle is small, then the stable tapping is possible in the Earth's gravity field.

Singly charged vanadium cluster ions from an external laser-vaporization source are accumulated in a Penning trap. They are subjected to electron bombardment which leads to further ionization. The charge states produced are analyzed by time-of-flight mass spectrometry after axial ejection from the trap. The results include the observation of charge states up to z = 6 and indications for signals at z = 7 and 8. Clusters of a given charge state may be selected for further investigation adding a new dimension to future studies of stored cluster ions.
