 The understanding that the macroscopic
damage can be tracked down to a microscopic scale, where the initial
processes involving the elementary constituents are the same as those
studied in molecular physics and photochemistry, has been a key
development in the field of radiation damage [1]. In recent years we
have focused our interest in processes induced in isolated molecules by
soft X-ray, where the site and state of the energy deposition are well
defined and the following chain of processes are characterized by
coincidence techniques [2]. Now in order to address the effects of the
increasing complexity of the target and the role played by the
'environment' on the properties of the single molecule, a series of
studies of the fragmentation induced by low energy ions in homogeneous
and hydrated clusters has been undertaken. Moreover exploiting the
unique properties of the new Free Electron Lasers an investigation of
the photo stability of the building blocks of biological matter,
theDNA/RNA basis, has been performed. In the seminar the main
achievements of this activity of theRomegroup will be presented.
