Abstract :
The aim of the recoil separator ARES, installed at Louvain-la-Neuve, is to study (p,γ) reactions of astrophysical interest involving unstable nuclei. ARES is coupled to CYCLONE44, a cyclotron dedicated to the post-acceleration of intense low-energy radioactive ion beams. The first measurement using a 19Ne radioactive beam has been performed recently. The resonance strength of the state at 448 keV above the 19Ne+p threshold has been investigated and an upper limit ωγ⩽15.2 meV has been obtained. This first measurement with ARES has suggested some improvements to be performed to the separator, which are described in this paper.
