113Cd

113Cd is an isotope of cadmium. It is a stable nuclide, meaning it does not undergo radioactive decay. 113Cd is a naturally occurring isotope of cadmium, found in small abundances alongside other cadmium isotopes. Its atomic number is 48, indicating it has 48 protons in its nucleus. The mass number, 113, signifies that a nucleus of 113Cd contains a total of 113 protons and neutrons. Specifically, it has 48 protons and 65 neutrons. While considered stable, 113Cd is weakly radioactive with a very long half-life, undergoing beta decay to the stable isotope 113In. This decay process is extremely slow, making it effectively stable for most practical purposes. The neutron capture cross-section of 113Cd is notably high, meaning it readily absorbs neutrons. This property is relevant in nuclear reactor design and neutron shielding applications. It is sometimes used in neutron activation analysis due to its distinctive gamma-ray emission upon neutron capture. Research into the properties and applications of 113Cd continues, particularly in areas related to nuclear physics and materials science.
