Interesting new theory papers are the Dupays work on hydrogen isotopic effects on O/N transfer and the follow up work by the Kansas group. From the Dupays paper PRL 93 (2004) 43401 one gets the impression that everything is solved and fine. However, Le and Lin from Kansas State point out that they calculate a much large p-wave resonance effect for O, inconsistent with Dupays. Moreover, they point out that the important p-wave effect is substantially modified by electron screening, an effect ignored by Dupays. There final results for mup->mO transfer is 4.42 compared to the experimental 8.5 E10/s. So the dust has not settled yet.
