Abstract
The growth of small tellurium clusters in helium and the influence of a met al impurity (dysprosium atoms) on the cluster size distribution are investi gated in a double laser vaporization source. A model describing the role of the carrier gas as collision partner is presented, emphasizing the crucial influence of the gas pressure on cluster formation. Changes in cluster rea ctivity due to dysprosium addition are discussed in terms of ionic structur es Dy3+(Te-N)(3-) containing a radical electron.
