Question

when lambda is emitted by an unstable nucleous............

Answer 1

Radioactive decay (also known as nuclear decay, radioactivity or nuclear radiation) is the process by which an unstable nuclear nucleus loses energy by emitting radiation (such as in its remaining frame), such as alpha particles, neutrino With a beta particle or a neutrinos in case of electron capture only, or a gamma ray or electron in the case of internal conversion. The material containing such an unstable nucleus is considered radioactive. Some exaggerated short-term nuclear states may decay through proton emission or, rarely, neutron emissions.
