Observation of nonstatistical ortho-para ratio in hydrogen recombination at low temperatures
Abstract
We have demonstrated that the molecular hydrogen obtained from atomic recombination at 300 mK has nonstatistic ortho-para ratio. The ortho para conversion is less than 3% in the vibrational relaxation phase. We suggest that it is possible to carry out detailed comparison between calculations and measurements at conditions similar to our experiments.
