Abstract

We measured in a molecular beam experiment the magnetic field dependence of the last bound levels of the X1Σg+ and a3Σ+u potentials close to the 3s+3s asymptote of Na2. The field behavior of these levels in an external magnetic field differs for even or odd nuclear mechanical angular momentum. Coupled channel calculations using high precision potentials for the X1Σg+ and a3Σ+u potentials gives excellent quantitative agreement between experiment and theory. Our data leads to a precise and quantitative description of the magnetic decoupling of the singlet and triplet manifold and of Feshbach resonances in a cold atomic collision.
