Deconfinement phase transition in QCD with heavy quarks
Using the pseudo-fermion method to simulate QCD with dynamical quarks we investigate the effects of heavy dynamical quarks of 2 flavours on the deconfinement phase transition in the quenched QCD. As the mass o...

Observation of small metastable multiply charged CsI clusters embedded inside rare gas clusters
Medium size Kr and Ar clusters 〈N〉 ~ 200 – 400 were used to pick up and aggregate CsI molecules. By varying the number of pick-up events it was possible to change the size of the guest cluster and the thickness o...

Aggregation of small CsI clusters inside Ar clusters: ionization and fragmentation under soft X-ray excitation
Medium size Ar clusters 〈N〉 ~ 500 were used to pick-up and aggregate CsI molecules. The primary Ar cluster beam can he converted into a beam of bare or Ar-covered alkali halide clusters by varying the number of p...
