138Ce
Cerium-138 (138Ce) is a stable isotope of the element cerium (chemical symbol Ce) with atomic number 58. It has 58 protons and 80 neutrons. In nature, 138Ce occurs as one of the natural cerium isotopes, but it is present at a far lower abundance than the most common isotopes of cerium.
As a stable, even-even nucleus, 138Ce does not undergo radioactive decay under normal conditions, and it has
Natural occurrence and abundance: cerium in nature exists as a mixture of isotopes, with 138Ce representing
Nuclear data and methods: 138Ce is identified and quantified using high-precision mass spectrometry and related analytical
Applications: isotopic compositions of cerium, including 138Ce, are used in geochemistry, cosmochemistry, and geochronology to study
