Fission times of uraniumlike nuclei with excitation energies up to about 250 MeV have been inferred from blocking effects in a single crystal. They are found longer by at least 1 order of magnitude than the ones obtained by other techniques, a hint f

We have performed a channelling experiment in which a ion beam, extracted by radiative recombination from the storage ring ESR at GSI after deceleration and cooling, was directed onto a thin silicon crystal. The directional properties of channelling

A cooled beam of decelerated highly-charged heavy ions is slowly extracted out of the cooler and storage ring ESR, by combining the deceleration technique and the charge exchange extraction mode. The quality of the external ion beam is tested by a ch

We have performed K-shell radiative electron capture (K-REC) measurements with bare 60.1-MeV/u incident krypton ions, both in channeling conditions and for random orientation of a 37-\ensuremath{\mu}m silicon crystal. The sampled electron densities a

Although high electronic excitations were neglected for a long time in radiation effect studies of metallic targets, it is now well established that they can play a dominant role in the damaging processes of some metals. Iron is especially interestin

Two aspects of heavy ion channeling are presented. The first aspect is related to the fact that channeled ions interact only with the most loosely bound target electrons. One can take benefit of this feature to study processes such as radiative elect

Pure bismuth samples were irradiated at 20 K with swift heavy ions from 18O to 238U in the GeV range. The rate of the induced damage was deduced from in situ electrical resistance measurements. Above a threshold in the electronic stopping power Se eq

Thin films of the Fe60Co40 alloy produced by electron beam deposition under ultrahigh vacuum have been irradiated at liquid nitrogen temperature with high energy ions, 40–186 MeV N ions and 445 MeV Ag ions, on the French accelerator GANIL in Caen.

The damage production in Fe 60 Co 40 thin films has been studied at liquid nitrogen temperature during low energy (15–360 keV He + , Ne + , Ar + , Xe + ) and high energy ion irradiations (445 MeV Ag ions, 186 MeV and 40 MeV N ions). The irradiated
