Isotope effect for associative detachment: H(D)− + H(D) → H2(D2) + e−

Miller, K. A.; Bruhns, H.; Čížek, M.; Eliášek, J.; Cabrera-Trujillo, R.; Kreckel, H.; O’Connor, A. P.; Urbain X.; Savin, D. W.

We report experimental and theoretical results for associative detachment (AD) of D− + D → D2 + e
−.
We compare these data to our previously published results for H− + H → H2 + e
−. The measurements show no
significant isotope effect in the total cross section. This is to be contrasted with previously published experimental
and theoreticalwork which has found a significant isotope effect in diatomic systems for partialADcross sections,
i.e., as a function of the rotational and vibrational levels of the final molecule formed. Our work implies that
though the rovibrational distribution of flux is different for AD of H− + H andD− + D, the total flux for these
two systems is essentially the same when summed over all possible final channels.
