WebThe n=2 triplet P fine structure of atomic helium is being measured using microwave transitions. The method [1] of Frequency-Offset Separated Oscillatory Fields (FOSOF) is used to perform the measurements. The measurement of the J=1-to-J=2 interval has been completed [2], with a measurement uncertainty of only 25 Hz. Web11 mei 2024 · Now, researchers have created and interrogated a novel kind of helium atom in which one of the electrons is replaced by a sub-atomic particle known as a pion. The work could shed light on the nature of both pions and neutrinos – tiny, neutral particles for which certain attributes, including mass, remain relatively poorly understood.
