Excitation of Simple Atoms by Slow Magnetic Monopoles
We present a theory of excitation of simple atoms by slow moving massive monopoles. Previously presented results for a monopole of Dirac strength on hydrogen and helium are reviewed. The hydrogen theory is extended to include arbitrary integral multiples of the Dirac pole strength. The excitation of helium by double strength poles and by dyons is also discussed. It is concluded that a helium proportional counter is a reliable and effective detector for monopoles of arbitrary strength, and for negatively charged dyons.

While we think that such a term should not be included in our treatment, to be on the safe side we have verified that it also satisfies the selection rule.ADSCrossRefGoogle Scholar
- 7.We are using the phrase “quasi adiabatic” to refer to a situation in which relative velocities are slow enough to allow us to assume that excitations are dominated by transitions to levels whose energy separation from the incident state is small compared to the minimum excitation energy which would be required for the isolated atom. The transitions are actually non-adiabatic.Google Scholar
- 9.In DKMPR we discussed this problem in a reference frame in which the nucleus was fixed at the origin. This made it natural to use as the perturbation Hamiltonian the change in H due to the addition of a point magnetic dipole instead of a point electric dipole. That is to say, in place of He we used That the two must give the same result follows from and = 0 for any eigenstate of H.Google Scholar
- 11.There are four additional excitation states, including the 3F4 state to which all excitation occurs at zero impact parameter, which are not included in the lower Paschen-Bach multiplet discussed in the text. Their total contribution to the cross section is much smaller.Google Scholar
