Neodymium-163

Properties and data of the isotope 163Nd.

Contents
General Data
Radioactive Decay
Isotones und Isobares

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.
