Near-threshold resonance helps explain a controversial measurement of exotic decay in beryllium-11
Most mass in everyday matter around us resides in protons and neutrons inside the atomic nucleus. However, the lifetime of a free neutronone not bounded to a nucleusis unstable, decaying by a process called beta decay. For neutrons, beta decay involves the emission of a proton, an electron, and an anti-neutrino. Beta decay is a common process.
