Isotope effect in the work function of lithium
Atef A. Sheekhoon, Abdelrahman O. Haridy, Vitaly V. Kresin
The work functions of 7Li and 6Li metals have been measured as a function of temperature, by using photoionization of pure isolated metal nanoparticles in a beam. These data reveal…
Reflections on future problems in cluster science
K. Hansen, V. V. Kresin, R. Alhyder +22
This article is a collection of contributions from speakers at the 2025 DEAMN [Dynamics of Electrons in Atomic and Molecular Nanoclusters] workshop at the Majorana Centre in Erice.…
Temperature-dependent photoionization thresholds of alkali-metal nanoparticles reveal thermal expansion and the melting transition
Abdelrahman O. Haridy, Atef A. Sheekhoon, Vitaly V. Kresin
A precision measurement of the photoionization of pure sodium and potassium nanoparticles isolated in a beam enabled an accurate determination of their work functions as a function…
Photoionization of temperature-controlled nanoparticles in a beam: Accurate and efficient determination of ionization energies and work functions
Atef A. Sheekhoon, Abdelrahman O. Haridy, Sebastian Pedalino +1
A beam of free alkali metal nanoparticles is produced by a condensation source, passed through a thermalizing tube adjustable over a broad temperature range, and ionized by tunable…
Stern-Gerlach deflection of cryogenically cold polyatomic molecules in superfluid nanodroplets
Benjamin S. Kamerin, Thomas H. Villers, John W. Niman +3
Beam deflection is capable of providing valuable information about the magnetic moments of molecules and clusters as well as the relaxation dynamics of their spins. However, observ…
Magnetic deflection of high-spin sodium dimers formed on helium nanodroplets
Thomas H. Villers, Benjamin S. Kamerin, Vitaly V. Kresin
Spectroscopic data on alkali-atom dimers residing on the surface of liquid helium nanodroplets have revealed that they are detected primarily in the weakly bound, metastable, spin-…
