Accelerator mass spectrometry

Definition

Accelerator mass spectrometry (AMS) is a sensitive technique used to measure the abundance of isotopes, particularly rare isotopes, by accelerating ions to high energies and analyzing them in a mass spectrometer. This method allows for precise measurements of isotopic ratios, which is crucial for studying exotic nuclei and superheavy elements, as it provides insights into their formation, stability, and decay processes.
