Abstract
Helium-3 was implanted into tantalum and aluminum foils at implant ene rgies ranging from 7 to 20 keV and with ion fluences exceeding 10(19) ions/cm(2) for the purpose of producing targets for nuclear reaction e xperiments. The effects of implant energy, fluence, and temperature on target thickness were studied. The foils were bombarded with deuteron s to initiate the He-3(d,p)He-4 reaction near the 430 keV resonance to determine target thicknesses, thickness lifetimes, and to study the p roperties of this reaction as a polarization analyzer. Results indicat e that these targets can be used in an efficient low-energy polarizati on analyzer.
