The Linear Zeeman effect in the molecular positronium Ps2 (dipositronium)

Miller, Daniel L.

Published Mar 29, 2015• 0 citations

Abstract

The linear Zeeman effect in the molecular positronium Ps2 (dipositronium) is predicted for some of $S=1$, $M=\pm1$ states. This result is opposite to the case of the positronium atom; the latter has only quadratic Zeeman effect.

Quadratic Zeeman effect in positronium

Gerald Feinberg, A. Rich, Joseph Sucher

The orbital ${\mathrm{\ensuremath{\mu}}}_{\mathit{L}}$\ensuremath{\cdot}B and diamagnetic ${\mathit{A}}^{2}$ interactions of electrons and positrons with an external magnetic field lead to a small quadratic Zeeman shift in the L=0, ${\mathit{m}}_{\mathit{S}}$=\ifmmode\pm\else\textpm\fi{}1 states of positronium, which, unlike the ${\mathit{m}}_{\mathit{S}}$=0 states, are not affected by the usual, spin-induced Zeeman shifts. For the n=1 states, this shift would be about 2 kHz in a field of 1000 G. These additional shifts are the same in all spin states for L=0 but do depend on n.

By taking advantage of the n 4 scaling factor, the quadratic Zeeman effect was measured for low magnetic fields in Rydberg states with principal quantum numbers n>100. The observed l-mixing is found to be in agreement with theoretical predictions.
