Laser spectroscopy of long-lived antiprotonic and pionic helium in superfluid helium
The PiHe collaboration of PSI recently carried out laser spectroscopy of an infrared transition in three-body pionic helium atoms that were synthesized in a superfluid (He-II) helium target. Analogous measurements of antiprotonic helium atoms embedded in liquid helium were carried out by the ASACUSA...
