【 摘 要 】

Synopsis Due to the dominant electron capture from its hull, C60acts like a spherical diffractor inducing resonances in the positronium (Ps) formation as a function of the positron impact energy. Results open new avenue of Ps spectroscopy with nanomaterials and push the barrier to motivate level-differential measurements.
