These timekeepers are based on precise knowledge of the frequency of
specific transitions between defined
energy levels in the
electron shells of certain atoms.
These
electrons, known as photoelectrons, have a very
specific energy of 24.1 electronvolts, which means they can be traced by the CAPS instrument, and easily distinguished from other
electrons, as they propagate through the surrounding magnetic field.»
