Work with a Unique Isotope of Hydrogen Generates Attention in the Scientific Community

By delving into the interactions between a hydrogen molecule and muonic hydrogen, the heaviest hydrogen isotope to date, a team of researchers from academia and Pacific Northwest National Laboratory created a popular paper. The article describes the kinetic isotope effects for muonic hydrogen and deuterium, which differ in mass by a factor of 36.  The article was one of the 20 most accessed articles in the November 2011 on The Journal of Chemical Physics.  The article's popularity, in part, is because it provides a more detailed account of work published in the prestigious journal, Science.

"It's amazing to me that such a simple reaction can continue to surprise and fascinate us," said Dr. Bruce Garrett, a co-author on this popular paper and the director of PNNL"s Chemical &   Materials Sciences Division.
