Neodymium-163

Properties and data of the isotope ¹⁶³Nd.

Content

Neodymium-163 is a radioisotope of the chemical element neodymium, which has 103 neutrons in the atomic nucleus in addition to the element-specific 60 protons, resulting in the mass number 163. The very short-lived, only artificially producible, unstable and therefore radioactive nuclide has no practical significance; dealing with ¹⁶³Nd is for academic purposes only.
