    • Abstract
  • A 15O secondary beam was produced via 2H( 14N, 15O*)n reaction in inverse kinematics on the secondary beam facility at the HI-13 tandem accelerator. The energy of the 15O secondary beam is (74.3±0.7) MeV, with a purity of 50% and the intensity of about 80 pnA -1·s -1 after collimation. We plan to use the 15O beam to measure key reactions involved in the nucleosynthesis process at several high-temperature astrophysical sites.
