Coulomb fission in multiply charged molecular clusters: Experiment and theory.
A series of three multiply charged molecular clusters, (C6H6)nz+ (benzene), (CH3CN)nz+ (acetonitrile), and (C4H8O)nz+ (tetrahydrofuran), where the charge z is either 3 or 4, have been studied for the purpose of identifying the patterns of behaviour close to the charge instability limit. Experiments show that on a time scale of ∼10-4 s, ions close to the limit undergo Coulomb fission where the o...
متن کاملStructure and dynamics of alkali-metal clusters and fission of highly charged clusters
A dynamical optimization of the minimum energy cluster structures of Na, K, Rb, and Cs clusters was performed using a many-body potential based on local density calculations. The energetics and vibrational analysis of the neutral clusters in the size range 8,N,310 were calculated, including the free energy as a function of the cluster size and the melting temperature. The fission process due to...
متن کاملCharge localization in multiply charged clusters and their electrical properties: some insights into electrospray droplets.
The surface composition of charged Lennard-Jones clusters A(N) (n+), composed of N particles (55 ≤ N ≤ 1169) among which n are positively charged with charge q, thus having a net total charge Q = nq, is investigated by Monte Carlo with Parallel Tempering simulations. At finite temperature, the surface sites of these charged clusters are found to be preferentially occupied by charged particles c...
متن کاملGeneration of charged droplets by field ionization of liquid helium
Positively charged helium droplets were produced by ionization of liquid helium in an electrostatic spraying experiment, in which fluid emerging from a thin glass capillary was ionized by applying a high voltage to a needle inside the capillary. At 2.2 K, fine droplets (<10 μm in diameter) were produced in pulsed sprays or showers with total currents as high as 0.4 μA at relatively low voltages...
متن کاملFemtosecond ionization of magnesium clusters grown in ultracold helium droplets
Magnesium clusters grown in helium droplets and ionized with femtosecond laser pulses have been studied by high resolution mass spectrometry. For moderate laser intensities the abundance spectra show characteristic features indicating electronic shell effects. Compared to clusters of s–electron metals additional shell closures appear resulting from an electron rearrangement. Irradiation with hi...
