Nonlinear Zeeman effect in photoassociation spectra of ${}^{40}$Ca near the ${}^3$P${}_1$+${}^1$S${}_0$ asymptote

Abstract

We present calculations of the Zeeman effect of narrow photoassociation lines of ${}^{40}$Ca near the ${}^3$P${}_1$ + ${}^1$S${}_0$ asymptote. Using a coupled-channel model we find a nonlinear Zeeman effect that even at low fields of a few mT amounts to several kHz. With this model we analyze previous measurements and give corrected long range dispersion coefficients of the ${}^3{\Pi }_u$ and ${}^3{\Sigma }_u^{+}$ states.
