摘要: In many antihydrogen trapping schemes, antiprotons held in a short-well Penning–Malmberg trap are released into longer well. This process necessarily causes the bounce-averaged rotation frequency Ω¯r of around axis to pass through zero. presence transverse magnetic multipole, experiments and simulations show that (over 30% some cases) can be lost hitherto unidentified bounce-resonant when is close
