Evidence for magic numbers of free lead-clusters
Abstract
Microclusters Pb n have been generated by condensation of lead atoms in cold He-gas. Electronic time-of-flight mass spectra show resolved peaks up to n ≈ 110 with pronounced size dependent structure up to n = 20. The magic numbers n ∗ = 7, 10, 13, 17 and 19 are deduced from the spectra.
