A modified version of a spectroscopic technique used at large-scale radioactive-ion-beam facilities could be used in tabletop experiments.
Optical spectroscopy provides an important window into the atomic and subatomic world. It can be applied to determine nuclear, atomic, and molecular structures, to test fundamental physics theories, and to track radioactive isotopes for environmental, geological, and medical applications. Recently, researchers have developed spectroscopic methods with exquisite precision and sensitivity, which allow them to study rare or short-lived isotopes at the edge of nuclear stability. Read more.
