Resonant ddμ Formation in Condensed Deuterium
A. Adamczak, M. P. Faifman
Abstract
The rate of ddμ muonic molecule resonant formation in dμ atom collision with a condensed deuterium target is expressed in terms of a single-particle response function. In particular, ddμ formation in solid deuterium at low pressures is considered. Numerical calculations of the rate in the case of fcc polycrystalline deuterium at 3 K have been performed using the isotropic Debye model of solid. It is shown that the energy-dependent ddμ formation rates in the solid differ strongly from those obtained for D2 gaseous targets, even at high dμ kinetic energies. Monte Carlo neutron spectra from dd fusion in ddμ molecules have been obtained for solid targets with different concentrations of ortho-D2 and para-D2. The neutron time spectra calculated for pure ortho-D2 and para-D2 targets are very similar.
