Abstract:

Molecular photodynamics in cryogenic solids are pursued in an effort to character the many-body interactions and dynamics that will control the possibilities of preparing, stabilizing, and subsequently using doped solid H2 as a propellant. While many of the experiments carried out involve inert rare gases, the photophysics sought in these experiments and theoretical developments form the fundamentals that transcend the specific host. In this class of issues are a how to describe the interactions of open shell atoms, which by definition will be the nature of dopants in propellants b development of a basic understanding for the relation between pair potentials and free energy, which controls diffusion kinetics of dopants in compressible solids c to develop time resolved experimental tools to interrogate these in detail d finally, we have carried out studies in one of the candidate systems, namely O doped solid D2. Aspects of this work have already been published. A list of the 1993-1994 publications from our group is included, all of this work has resulted either from the URI or the earlier funded AF contract on HEDM from the Phillips Laboratory.
