neodymium146

Neodymium-146 is a stable isotope of the element neodymium. Neodymium (Nd) is a chemical element with the symbol Nd and atomic number 60. It is a member of the lanthanide series. Neodymium-146 has a mass number of 146, meaning it has 60 protons and 86 neutrons in its nucleus. It is one of the seven naturally occurring stable isotopes of neodymium, making up approximately 17.2% of the natural abundance of neodymium. Its nuclear spin is 0, and it has no magnetic dipole moment. Neodymium-146 is not radioactive.

The abundance of neodymium-146 plays a role in geological dating and tracing. Variations in the isotopic composition of neodymium, including the relative amounts of neodymium-146, can be used to study the age and origin of rocks and minerals. These isotopic signatures can provide insights into the Earth's mantle evolution and crustal processes. In scientific research, neodymium isotopes are sometimes used as tracers in environmental studies and in the analysis of materials. The stability of neodymium-146 means it is not subject to radioactive decay, simplifying its use in applications where a non-radioactive isotope is required.
