The growth of small tellurium clusters in helium and
the influence of a metal impurity (dysprosium atoms) on the cluster size
distribution are investigated 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 reactivity due to dysprosium
addition are discussed in terms of ionic structures 
containing a radical electron.
