Author(s): B. S. Cooper, J.-P. Boilot, C. Corbel, F. Guillemot, L. Gurung, L. Liszkay, and D. B. Cassidy We report experiments in which positronium (Ps) atoms were created in thin, porous silica films containing isolated voids with diameters ranging from 5 to 75 nm. Ps lifetimes in the pore structures were measured directly via time-delayed laser excitation of 1 3 S 1 → 2 3 P J transitions. In a film containin... [Phys. Rev.
