An experiment of X-ray photon-photon elastic scattering with a Laue-case beam collider
T. Yamaji, T. Inada, T. Yamazaki +9
We report a search for photon-photon elastic scattering in vacuum in the X-ray region at an energy in the center of mass system of ω_{cms} =6.5 keV for which the QED cross section…

Study on Cooling of Positronium for Bose-Einstein Condensation
Kenji Shu, Xing Fan, Takayuki Yamazaki +4
A new method of cooling positronium down is proposed to realize Bose-Einstein condensation of positronium. We perform detail studies about three processes (1) thermalization proces…

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…
