The weak binding of preformed metallic clusters to atomically smooth substrates has presented an impediment to the study of supported nanometer-size clusters using scanning probe techniques. The sweeping of supported clusters on flat substrates by a scanning probe tip has been identified as a problem. Unless special precautions are taken, only those clusters pinned at defect sites are routinely...

Atomic nuclei can exhibit shape coexistence and multi-reference physics that enters in their ground states, to accurately capture the ensuing correlations entanglement is challenging. We address this problem by applying single-reference coupled-cluster theory based on spherical deformed reference states tailored method. The latter combines configuration interaction static with for dynamic corre...

We investigate the atomistic details of a single atom-extraction process realized by using the scanning tunneling microscope tip-cluster interaction on a Ag(111) surface at 6 K. Single atoms are extracted from a silver cluster one atom at a time using small tunneling biases less than 35 mV. Combined total energy calculations and molecular dynamics simulations show a lowering of the atom-extract...

Transmission electron microscopy has been used to observe craters produced 7 on Al, Cu and Au at room temperature by the impact of Ar clusters. Irradiations were made at normal incidence with Ar clusters of either 100 or 1000 atoms having an energy of 100 keV. The probability of a cluster to make a crater decreases with increasing target atomic mass or density, At a given total energy, the prob...
