M. Joppien et al., EXCITATION AND DECAY PROCESSES IN HELIUM CLUSTERS STUDIED BY FLUORESCENCE SPECTROSCOPY, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 26(1-4), 1993, pp. 382-384
Excitation and decay processes of helium clusters are investigated wit
h fluorescence methods. The results differ remarkably from that obtain
ed for the heavier rare gas clusters. They are discussed in view of th
e unusual structural and electronic properties of helium.
