Neodymium Isotopes are used in a variety of scientific applications. Nd-142 has been used for the production of short-lived Tm and Yb isotopes. Nd-146 has been suggested for the production of Pm-147 which can be used as a source for radioisotopic power generation. Several Nd isotopes have been used for the production of other Pm isotopes. Finally, Nd-150 has been used to study double beta decay.
