Abstract

A new method for stable and continuous doping of superfluid helium nanodroplets (HeN) with high-melting elements such as refractory metals is presented. The method exploits the advantages of electron bombardment heating and avoids stray fields induced by high currents or high frequency fields. It is thus especially suitable for magnetic studies of atoms and clusters in HeN. The source is characterized by means of mass spectroscopic investigations of HeN doped with chromium atoms and clusters. Source temperatures of up to (1650 ± 50) °C were reached and Cr clusters up to Cr9 could be formed in HeN.
