"Thermal Spike" model applied to thin targets irradiated with swift heavy ion beams at few MeV/u

International audienceHigh electronic excitations in radiation of metallic targets with swift heavy ion beams at the coulomb barrier play a dominant role in the damaging processes of some metals. The inelastic thermal spike model was developed to describe tracks in materials and is applied in this paper to some systems beams/targets employed recently in some nuclear physics experiments. Taking into account the experimental conditions and the approved electron-phonon coupling factors, the results of the calculation enable to interpret the observation of the fast deformation of some targets

Fusion cross section measurements of astrophysical interest for light heavy ions systems within the STELLA project

This contribution is focused on the STELLA project (STELlar LAboratory), which aims at the measurement of fusion cross sections between light heavy ions like 12C+12C, 12C+16O or 16O+16O at deep subbarrier energies. The gamma-particle coincidence technique is used in order to reduce background contributions that become dominant for measurements in the nanobarn regime. The experimental setup composed of an ultra high vacuum reaction chamber, a set of 3 silicon strip detectors, up to 36 LaBr3(Ce) scintillators from the UK FATIMA collaboration, and a fast rotating target system will be described. The 12C+12C fusion reaction has been studied from Elab = 11 to 5.6 MeV using STELLA at the Andromède facility in Orsay, France. Preliminary commissioning results are presented in this article

Methods of Targets' Characterization

International audienceThe paper reviews the characterization's techniques for solid targets used in nuclear physics with special emphasis on actinide targets. The determination of the thickness, isotopic and chemical composition are described for actinide targets during their fabrication process. Accent is given on their monitoring during irradiation

Preparation of osmium targets with carbon backing

International audienceFor nuclear reaction studies, thin metallic osmium targets, either natural or isotopically enriched (Os-192) of 200-300 \u03bcg/cm2 thicknesses deposited on a thin carbon backing are required. A challenging method was successfully performed at GANIL involving firstly the preparation of an aqueous solution of osmium tetrachloride, then its electro- deposition onto a thick copper backing (100 \u03bcm); this process was followed by the evaporation of a thin carbon layer (40 \u03bcg/cm2) and finally the dissolution of the copper material
