Abstract

The in-flight heavy-ion fragmentation technique has been used to produce a secondary beam of tritons (3H) at intermediate energies (Et > 100 MeV / nucleon) from primary 16,18O beams of 150 and 120 MeV/nucleon, respectively. The best results are obtained with a 16O beam of 150 MeV/nucleon, producing a 115 MeV/nucleon triton beam. The triton beam will be used in (t,3He) charge-exchange experiments at the S800 spectrometer at the NSCL. At the target of the S800, a triton rate of 5 × 106 particles per second is achieved, for a primary 16O beam of 100 pnA. The (t,3He) reaction using this beam was tested with a 24Mg target. An excitation-energy resolution of 190 ± 15 keV is achieved.
