Production of a low-energy radioactive nuclear beam with high purity using JAERI-RMS

Low-energy (1–2 MeV/nucleon) radioactive nuclear beams (RNBs) of 8Li, 12B and 16N have been produced through nuclear transfer reactions using a recoil mass separator (RMS) at Japan Atomic Energy Research Institute (JAERI). The contamination of the primary beam to the RNB was investigated quantitatively and was well suppressed. The typical beam intensities of 8Li-, 12B- and 16N-RNB were 1.4×1041.4×104, 7.8×1037.8×103 and 4.7×103pps, respectively. Their purities were 99%99%, 98%98% and 98.5%98.5%, respectively.
