Abstract

In order to obtain information on a possible two-neutron component in the ⁶He wavefunction, we investigated the ⁴He(⁶He, ⁶He)⁴He 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 ARENAS³ Radioactive Ion Beam Facility in Louvain-La-Neuve. We used a⁴He-implanted aluminium foil as a target. A ⁴He thickness of about 2-3 × 10¹⁷ particles/cm2 was obtained implanting ⁴He 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 ⁴He(⁶He, ⁶He)⁴He scattering. Our results demonstrate the possibility of using a ⁴He-implanted target in experiments with low-intensity beams, like radioactive beams, where deterioration of the target is irrelevant.
