Abstract. Mercury clusters have been ionised by impactof electrons of variable kinetic energy. For cluster sizes n < 540 a linear threshold law is observed, which allows an accurate identification of the ionisation energies. The differences to photo ionisation are discussed. Jellium like intensity variations are observed in the mass spectra, in a size region where the bonding in Hg clusters has not yet become metallic.
