Researchers Develop Method to Describe Binding of Protons and Neutrons

A researcher at North Carolina State University has helped to develop a new method for describing the binding of protons and neutrons within nuclei. This method may improve scientists' ability to predict and understand astrophysical reactions within stars.
When protons and neutrons bind, the process releases energy. This fusion energy is how stars burn. If scientists can determine where these particles are, what they are doing, and how they are binding, they will then be able to more accurately predict and understand the life cycles of stars.
NC State physicist Dr. Dean Lee and German colleagues Evgeny Epelbaum, Hermann Krebs, and Ulf-G. Meissner, set out to see if there was a more straightforward approach to describing particle interactions than currently used.
Their results were published in the April 9 issue of  Physical Review Letters.
