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…

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…
