For the Sun, we predict theoretical ratios of 21. 0 and 23. 7 ppm/[m/s] from BiSON and SONG respectively, in good agreement with observations 19. 1 and 21. 6 ppm/[m/s].

These experimental results place constraints on theoretical predictions of MN processes of Li$^+$ and Na$^+$ with H$^-$, important for non-LTE modelling of Li and Na spectra in late-type stars.
