Barrier to Aggregation for Light-Atom Dopants of Solid Hydrogen
Abstract
In this report the development of the use of spectroscopy in highly quantum clusters made of H2 or He to study the possibility to increase the energy contents of solid H2 by seeding in it, in a stable way, relatively high (^ 5%) of light metal atoms or complexes. Experimental results on the solvation (or lack of it) of metal atoms (Mg and Al) with both spherical (Mg) and not-spherical (Al) outer electronic shells are discussed and compared with theoretical predictions. Theoretical results on the improvement of models to calculate intermolecular potentials in hard atom-soft atom interactions are also discussed. Finally, the progress towards assembling a facility for Stimulated Raman Scattering measurements in molecular beams of doped and undoped H2 cluster is reported. The latter facility should enable the determination of several parameters for metal-doped condensed H2 which are essential to the determination of the viability of doped H2 as a rocket fuel.
