Even more information about the electronic structure of the clusters has been obtained now by angle resolved photoelectron spectroscopy, which in principle allows one to gain information about the character of the electronic wavefunctions. The results demonstrate that sodium clusters have an electronic structure close to that of an finite size free electron gas, which makes them perfect model systems for the study of many particle dynamics. One such measurement is the time-resolved study of the cooling of the hot electron gas in the cluster, which allowed to determine the size dependence of the electron phonon coupling strength.Read More
