Abstract

Solid 4He targets were prepared by implantation of He ions of various energies into thin Al foils. The targets were tested using the proton Rutherford backscattering (RBS) technique. The tests showed that a considerable amount of the implanted He atoms stays in the host foils for a long time after the implantation. A possibility of using the He-im-planted targets in experiments with radioactive beams is demonstrated. Further steps to increase He amount in th
