Spontaneous emission of radiation is the process that governs how matter scatter light making objects visible. Visibility is at the core of our senses and its control is amenable for microscopy, optomechanics and quantum information. In many quantum applications, it is accepted that the natural process of spontanoues emission sets the ...
Naturally occurring barium (56Ba) is a mix of six stable isotopes and one very long-lived radioactive primordial isotope, barium-130, identified as being unstable by geochemical means (from analysis of the presence of its daughter xenon-130 in rocks) in 2001. This nuclide decays by double electron capture (absorbing two electrons and emitting two neutrinos), with a half-life of (0.5–2.7)×10 years (about 10 times the age of the universe). WebbAll important properties of barium and its compounds. Chemical properties of barium. Barium is no less reactive than alkaline metals such as sodium or potassium. When heated in air, the metal may ignite, and on contact with oxygen, it may oxidize to barium oxide BaO (in air barium nitride Ba₃N₂ may also form).
