The Big Bang. That spontaneous explosion some 14 billion years ago that created our universe and, in the process, all matter as we know it today.
View ArticleThe intriguing interplay between collective and single-particle excitations...
Nuclear reactions are among the most important processes that drive our Universe. In our Sun nuclear fusion provides the energy for the sun to radiate. In more violent cosmic events neutron capture...
View ArticleModernizing the format of nuclear data
When atomic nuclei collide with other nuclei or subatomic particles, a large number of reactions can occur, resulting in many possible products. High-quality data describing these nuclear reactions are...
