strongly disagree with the ab initio values of Jönsson et al. [J. Phys. B: At. Mol.
Opt. Phys. 43, 115006 (2010)].
We propose a new interpretation of the recorded weak spectral lines. If the latter are indeed reinterpreted as crossover signals, a new set of experimental hyperfine constants is deduced, in very good agreement with the ab initio predictions.
