The proton-proton chains (p-p chains), a series of nuclear reactions were proposed several decades ago as a way in which hydrogen burning can occur in smaller main sequence stars. The 3He + 4He? 7Be reaction determines the path that the p-p chains follow. At present the cross section for this reaction has not been precisely determined. To measure this cross section a 3He target and 4He beam are to be used. 3He exists as a gas so a method to manufacture a solid 3He target was needed. A 3He beam was used to implant 3He into Aluminum to make a solid 3He target. This paper reports measurements of the composition of targets made by 3He implantation into Aluminum.
