Time independent description of thet(d,n)α fusion reaction in the presence of a muon

We describe the (α n μ)—(d t μ) continuum above and below thed+(t μ)₁ s threshold using theR-matrix formalism. The continuum is explicitly constructed in an adiabatic approximation, and the asymptotic phase shifts and amplitudes in all channels are obtained. The energy eigenstates are used to compute the fusion reaction cross section for in-flightd+(t μ) fusion, and fusion reaction rates involving transitions from thed+(t μ)₁ s continuum to be below threshold continuum states.
