Search for Photon-Photon Elastic Scattering in the X-ray Region
T. Inada, T. Yamaji, S. Adachi +9
We report the first results of a search for real photon-photon scattering using X rays. A novel system is developed to split and collide X-ray pulses by applying interferometric te…

First Millimeter-wave Spectroscopy of the Ground-state Positronium
A. Miyazaki, T. Yamazaki, T. Suehara +7
We report on the first measurement of the Breit-Wigner resonance of the transition from {\it ortho-}positronium to {\it para-}positronium. We have developed an optical system to ac…
