Hyperspherical calculations of low-energy rearrangement processes indtμ

The results of accurate hyperspherical calculations of the reaction dμ(ni)+t→tμ(nf)+d between states of the ni=nf=1 and ni=nf=2 manifolds for zero total angular momentum of the collision system are reported. A parametrization of the threshold behavior of the ground-to-ground?state muon transfer cross section in the spirit of the effective range theory is discussed
