✦ Synopsis

Very high fluence implantation of 7 Li + ions was used to promote the formation of a thin and high density 7 Li target in the surface region of Al samples. The implanted volume was characterized by particle induced gamma-ray emission, Rutherford backscattering spectrometry, X-ray photoelectron spectroscopy and nuclear reaction analysis, revealing that the implanted surface is a combination of Li 2 CO 3 , metallic lithium, LiOH and C, with almost no Al present. Radiation damage effects by proton beams were studied by observing the evolution of the 7 Li(p, a) 4 He nuclear reaction yield with the accumulated charge, at different proton energies, revealing high stability of the produced Li target.
