Photodisintegration sum rule and electron distribution in metal clusters

Technical Report:

Abstract

The inverse energy-weighted photodisintegration sum rule is investigated. This quantity can be reliably extracted from experimental measurements of the cluster photoabsorption cross section {sigma}({omega}), which is shown to reflect the strongly correlated character of the motion of valence electrons. A model-independent relation between {sigma}{sub -1} and the amplitude of the zero-point motion in the dipole mode is derived. Theoretical results for the sum rule are discussed and compared with experimental data. An expression for the mean distance between two electrons in a cluster is derived. (author) 12 refs.; 1 tab.
