In stars, three of them react to form carbon in a process that occurs at extreme temperatures and low hydrogen concentrations.
Considering one of these particles as a particle-in-a-box allows you to derive the Geiger-Nuttall law, which relates lambda to the energy of these particles. In stars, three of them react to form carbon in a process that occurs at extreme temperatures and low hydrogen concentrations. The fact that some of these particles were deflected when Marsden and Geiger shot them at a metal sheet was evidence for the existence of the atomic nucleus. For 10 points, name these particles equivalent to helium nuclei, the largest particles produced during radioactive decay.
