Magnetically bound states of electronic and positronic hydrogen ions: The case of zero orbital angular momentum
- Department of Physics, University of California at San Diego, La Jolla, California 92093 (United States)
This paper considers the binding of an electron or a positron to a ground-state hydrogen atom in a uniform magnetic field B, concentrating on states with zero orbital angular momentum J. It is shown that the affinity of a positron to a hydrogen atom is 2.23b{sup 2}e{sup 2}/a, where a is the Bohr radius, b{identical_to}B/B{sub 0}, B{sub 0}=2.3505x10{sup 5} T, b<<1 is assumed, and the proton is assumed to have infinite mass. With these assumptions it is also shown that no J=0 singlet or triplet excited state of H{sup -} exists. These results are compared to a previous estimate of the electron affinity of J=0 magnetically bound ions [V. G. Bezchastnov, P. Schmelcher, and L. S. Cederbaum, Phys. Rev. A 61, 052152 (2000)].
