Toshio Hyodo is a Professor at the Institute of Material Structure Science, High Energy Accelerator Research Organization and a Professor Emeritus at the University of Tokyo. He is ex-Chair of the International Advisory Committee on Positron Annihilation and the current President of the Japanese Positron Science Society. He received his Ph.D. from the University of Tokyo in 1979 for his experimental work on positron annihilation in solids. During 1980–1982 he was a visiting researcher at the Physics Department of Queen’s University, Canada. His research interests include positronium (Ps) states in solid materials and Ps interactions with molecules and solid surfaces using silica aerogel as a Ps formation medium, as well as slow positron beam instrumentations. He is also actively interested in the improvement of physics education.


In tight spaces

Laser spectroscopy of positronium confined to nanoscale pores is a tool to probe the size of buried cavities and a step toward the long-term goal of a positronium BEC. Read More »
