Abstract: | Since it has been demonstrated that antiprotons can be captured in sizeable amounts in ion traps, the intriguing question
has been raised whether or not these antiprotons can be used for producingantihydrogen atoms. One route proposed is the merging of trapped antiprotons with a cold trapped plasma of positrons. In this case the formation
of antihydrogen proceeds most likely through three-body recombination (p−e+e+→
e+) into high Rydberg states of
, followed by a rapid cascade of transitions to low-lying states. To assess the influence of the trapping magnetic field (on
the order of a few tesla) upon the formation process of
we review the present knowledge of the behaviour and properties of hydrogen (and antihydrogen) atoms in strong magnetic fields
— a subject which has been very topical in recent years because of its relation to the problem of “quantum” chaos. |
