145Nd

145Nd, or neodymium-145, is a radioactive isotope of the element neodymium (Z = 60) with a mass number of 145 (N = 85). It is not naturally abundant and is produced in nuclear reactions, such as neutron capture on nearby neodymium isotopes or during spallation and fission processes in reactors and accelerators.

The primary decay mode of 145Nd is beta-minus decay to 145Pm (promethium-145), often accompanied by gamma emissions. Its half-life is relatively short, varying over measurements and states, and it is studied mainly for nuclear physics research rather than practical applications.

In research settings, 145Nd is used to investigate beta decay properties, nuclear structure, and reaction mechanisms. Because it is radioactive, handling and experiments involving 145Nd require appropriate radiation safety measures and containment. While several neighboring neodymium isotopes include stable forms such as 142Nd, 143Nd, 144Nd, 146Nd, 148Nd, and 150Nd, 145Nd itself does not occur naturally in appreciable amounts and is primarily encountered in laboratory-produced samples.
