Typical activities of the research groups at HIL

• GDR studies• γ-γ in-beam spectroscopy• Life time measurements (e.g. with DSA

method)• Multiple Coulomb excitation studies• On-line β internal conversion spectroscopy• Reactions with light ions • Fusion barrier height distribution studies• Biological interactions of high LET radiation

studies• Irradiations of solid state materials with

heavy ions• Semiconductor detectors development and

tests

• About 1 200 hours of beam-on-target time in 2006 was used by internatio-nal users.

• All projects performed at HIL are evaluated by international Program Advisory Committee.
