142Nd144Ndsample

142Nd144Nd sample refers to a specific isotopic composition of neodymium (Nd), a rare earth metal with the atomic number 60. Neodymium is known for its magnetic properties and is used in various applications, including magnets, lasers, and glass coloring. The notation 142Nd144Nd indicates that the sample contains two isotopes of neodymium: Nd-142 and Nd-144. Nd-142 has 82 neutrons, while Nd-144 has 84 neutrons. This specific isotopic composition is of interest in scientific research, particularly in the study of nuclear reactions and the behavior of rare earth elements under different conditions. The 142Nd144Nd sample is often used in experiments to understand the isotopic fractionation processes that occur in natural systems, such as in the Earth's mantle and crust. The isotopic ratios of neodymium are also used in geochronology and geochemistry to determine the age and origin of rocks and minerals. The study of 142Nd144Nd samples contributes to our understanding of the Earth's geological history and the processes that shape our planet.
