Science Highlights

Each year, scientists with the Office of Science, at our national laboratories, and supported by the Office of Science at the nation’s colleges and universities, publish thousands of research findings in the scientific literature. About 200 of these are selected annually by their respective program areas in the Office of Science as publication highlights of special note.

A photon is absorbed by the ground state of helium-4. This excites the transition to the first excited state of helium-4, which sits just above the energy threshold for separation into a proton and a hydrogen-3 nucleus.
New calculations confirm recent experimental results on the transition between the alpha particle and its first excited state.
