132Ba

132Ba is an isotope of the element barium (symbol Ba, atomic number 56) with a mass number of 132. It is not a stable nuclide and does not occur naturally in detectable quantities. The isotope has been studied in nuclear physics experiments and is typically produced as a short‑lived reaction product in fusion-evaporation, spallation, or neutron-induced reactions, or as a decay product of heavier nuclides.

Nuclear properties and decay: 132Ba lies far from the valley of stability. The ground-state decay mode is

Production routes: In laboratory settings, 132Ba can be created through spallation of heavier targets, projectile fragmentation

Chemical considerations: As an isotope, 132Ba shares the chemical properties of barium; its isotopic composition does
