👉 Tignon is a term used in the context of nuclear physics, specifically in the study of beta decay. It refers to the process by which a nucleus (such as a neutron) emits a proton and an electron in a process known as beta decay. Beta decay occurs when a neutron decays into two protons and an electron. In this process, the neutrons are released as alpha particles, while the electrons remain inside the nucleus. The resulting nucleus has a smaller mass than its predecessor due to
