Abstract / Description of output
In order to obtain information on a possible two-neutron component in the He wavefunction, we investigated the He(He, He)He elastic scattering at beam energies of 29.1, 29.6 and 40 MeV and at center-of-mass angles between 20 and 163 degrees. The experiments were performed at the ARENAS Radioactive Ion Beam Facility in Louvain-La-Neuve. We used aHe-implanted aluminium foil as a target. A He thickness of about 2-3 × 10 particles/cm2 was obtained implanting He nuclei at energies between 20 and 80 keV in 0.7-μm-thick foils. Data collected in a larger angular range than previous measurements give additional evidence for the 2n-transfer process to take place in the He(He, He)He scattering. Our results demonstrate the possibility of using a He-implanted target in experiments with low-intensity beams, like radioactive beams, where deterioration of the target is irrelevant.
