High accuracy photoassociation of 40Ca near the 3P1+1S0 asymptote and its Zeeman effect
Abstract
We report on the first measurement of narrow photoassociation lines of 40Ca near the 3P1+1S0 asymptote related to the molecular states 3u and 3+u. The highly accurate binding energies and Zeeman splittings are well described by a coupled channel theoretical model, confirming theoretical predictions of long-range coefficients. Our analysis shows that only the inclusion of both energies and Zeeman splittings provides an accurate description of the long-range interaction potentials.
