Microwave spectroscopy of positronium atoms in free space

HIGHLIGHTS

• who: R. E. Sheldon from the DepartmentUniversity College London, Gower Street, London WC E BT, England, United Kingdom have published the research: Microwave spectroscopy of positronium atoms in free space, in the Journal: (JOURNAL) of 18/04/2023
• what: The authors report measurements of the positronium (Ps) 2 3S1 u21922 3P2 interval in which atoms traveling in free space were irradiated with microwave radiation generated using a horn antenna. In the free-space measurements the authors report here much smaller line-shape asymmetry was observed but with large frequency shifts that varied with the orientation . . .
