Positrons, Quantum Crystals, and Nanoparticles (Oh My!) - Quantum Mechanics in Action at the USAF

Abstract : CONCLUSIONS: Solid parahydrogen produced by Rapid Vapor Deposition is amenable to Polarization Spectroscopy: Facilitates the assignment of the crystal field fine structure in the spectra of rotating dopants; * Sheds light on cluster formation in doped parahydrogen samples; * Provides new insight into the annealing behavior of the solid parahydrogen produced by RVD; * Electron and Positron irradiation of solid hydrogen presently underway.
