Quote: "Under ambient conditions, these dimers cannot be formed and investigated and one typically cools the atoms down to a very low temperature in order to form them." It therefore seems highly unlikely that they would form in a Papp style engine, especially as clusters are likely to be even harder to form than dimers.
