(deutsche Version unten) Neodymium (Nd) is one of the Rare Earth Elements (REE) and consists of seven isotopes. One of the isotopes, 143Nd, is a decay product of the samarium isotope 147Sm that also belongs to the REE with a half-life of 1.06×1011 years. Since the Sm/Nd ratio in rocks and minerals varies, there are […]
