Abstract: Muon reactivation coefficient are determined for muonic He$({\rm He} = {}^4_2 {\rm He} = \alpha, {\rm He} = {}_2^3 {\rm He} = h)$for up to six(n = 1, 2, 3, …, 6)states of formation and at temperatureTp= 100eV and for various relative ion densities. In the next decade it may be possible to explore new conditions for further energy gain in muon catalyzed fusion system,μCF, using nonuniform (temperature and density) plasma states. Here, we have considered a model for inhomogeneousμCFfor mixtures ofD/TandH/D/T. Using coupled dynamical equations it is shown that the neutrons yield per muon injection,Yn(neutrons/muon), in thedtbranch of an inhomogeneousH/D/Tmixture is at least 2.24 times higher than similar homogeneous systems and this rate for aD/Tmixture is 1.92. Also, we have compared the neutron yield in thedtbranch of homogeneousD/TandH/D/Tmixtures (temperature rangeT = 300–800K, and density ϕ = 1 LHD). It is shown thatYn(D/T)/Yn(H/D/T) = 1.32, which is in good agreement with recently measured experimental values. In other words our calculations show that the addition of protonium to aD/Tmixture leads to a significant decrease in the cycling rate for the physical conditions described herein.
