Influence of epithermal muonic molecule formation on kinetics of the μCF processes in deuterium

摘要

The non-resonant formation of ddμ molecules in the loosely bound state in collisions of non-thermalized dμ atoms with deuterium molecules D2 has been considered. The process of such a type is possible only for collision energies exceeded the ionization potential of D2. The calculated rates of ddμ formation in the above-threshold energy region are about one order of magnitude higher than obtained earlier. The role of epithermal non-resonant μ-molecule formation for the kinetics of μCF processes in D2 gas was studied. It was shown that the non-resonant ddμ formation by dμ atoms accelerated during the cascade can be directly observed in the neutron time spectra at very short initial times.
