The early E ⩽ 511 keV gamma-ray emission from novae depends critically on the F 18 ( p , α ) O 15 reaction. Unfortunately the reaction rate of the F 18 ( p , α ) O 15 reaction is still largely uncertain due to the unknown strengths of low-lying p

The 15O(α,α)15O elastic scattering is investigated using a 15O radioactive beam and a He gas cell limited by Mylar windows. The width of a 19Ne state at an excitation energy of 5.35MeV is measured as Γα = 3.2±1.6keV, in agreement with charge sym

The "manganese bath" technique has been perfected to measure the total number of neutrons emitted when 23-80 MeV proton beams bombard a beryllium target. It consists in surrounding the neutron source with a large metallic cylinder filled with a manga

The development of an intense and pure post-accelerated Be-7 beam at Louvain-la-Neuve will be discussed. Given its properties (metallic nature, long half-life (53 days)) and the special beam parameters required (multi-charge ions, high purity), a ran

At the end of 1999, a first on-line RIB was accelerated, extracted and separated with the new cyclotron, CYCLONE44. An efficiency of 7% (from ion source exit to experiment target), resulting in 6 x 10(8) pps of Ne-19(3+), was obtained. Up to 9 kW of

An efficient method for the production and post-acceleration of a pure F-18(T-1/2 = 109.8 min) radioactive beam has been developed. Large amounts of F-18 are produced via the O-18(p,n)F-18 reaction using a 15.5 MeV proton beam on an O-18-enriched wat

F-18 radioactive beams were used to measure the F-18(p,alpha) reaction in the c.m. energy ranges of 265-535 keV and 550-740 keV. In each case, a resonant level was clearly detected, of which the resonant strength and some other properties were deduce
