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.](/-/media/np/images/highlights/2024/FRIB-MSU-Alpha-Particle-Image.jpg?h=544&w=1430&la=en&hash=500911D9E1D55459F3E9C4B3925550F24761B8A72094DAEEDD51A503CE960475)
Exciting the Alpha Particle
New calculations confirm recent experimental results on the transition between the alpha particle and its first excited state.
