Nature of problem:
The introduction of a mu- particle into a mixture of hydrogen isotopes brings about a repetitive cycle of processes leading to nuclear fusion and the release of energy. Sticking is one of the critical processes limiting the number of fusions induced by one muon during its lifetime. When the (alpha mu)+ ion created with the energy E=3.46 MeV is slowed down in a dense D-T mixture, the muon can be stripped (reactivated), thus allowing the muon to return to the catalytic cycle.

Solution method:
The coupled differential equations describing the reactivation process are solved using the computer code as documented in: COMPUTER SOLUTION OF ORDINARY DIFFERENTIAL EQUATIONS: The initial value problem by L.F. Shampine and M.K. Gorden.
