Abstract

Nickel and cobalt clusters have been studied by near threshold laser-photoionization and time-of-flight mass spectrometry. In the size domain from 50 up to 800 atoms, the mass distributions of the photoionized products look very similar for nickel and cobalt clusters. In both cases a regular structure is observed which is periodic on a N1/3 scale. It is found to be consistent with the filling of successive icosahedral shells of atoms. The recurring details of this structure agree with the so-called umbrellas model.
