Xenon130

Xenon-130 is a stable isotope of the element xenon. Xenon is a noble gas with the chemical symbol Xe and atomic number 54. Naturally occurring xenon is composed of nine stable isotopes, with xenon-130 being one of them. It has a mass number of 130, meaning its nucleus contains 54 protons and 76 neutrons. Xenon-130 is the most abundant stable isotope of xenon, making up approximately 26.89% of the natural abundance of xenon.

This isotope has a very low neutron capture cross-section, which makes it useful in certain applications where neutron absorption is undesirable. It can be found in trace amounts in the Earth's atmosphere, originating from the decay of other radioactive isotopes and from cosmic ray interactions. Xenon-130 is not radioactive and does not undergo decay. Its properties are typical of other xenon isotopes, including its inert chemical nature due to its full outer electron shell. Research involving xenon isotopes often utilizes mass spectrometry to identify and quantify their presence, and xenon-130 is a common reference point in such analyses.
