Description
We present mutual neutralization studies of $^{1,2}$H$^-$ with Li$^+$, O$^+$, N$^+$ and C$^+$ at DESIREE. The systems are of astrophysical interest and the collisions take place at sub-electronvolt energies which are typical collision energies in cold stellar photospheres. The most prominent finding is a strong isotope effect on the branching fraction into Li(3s), which constitutes one of the first and only observations of its kind. We compare our results to theoretical predictions with varying degree of agreement.
