چکیده

Forced muon catalyzed fusion in the two layers of reactor, H/T and D2 ( with density \phi0 ), is proposed. After injection of muons into the H/T (localized at x= 0) , start slowing down and are finally captured by the atoms. This means that the muonic atoms are formed, i.e. t\mu (1s) . Due to Ramsauer-Townsend effect, the t\mu muonic atoms leave H/T and enter the second layer. The time-space dependent transport equations are applied and solved for the reactor media by Backward implicit method(BIM). The numerical method of BIM is used to obtain the number densities of N^E_\mu t (x, t) at the resonance collision energies E = 0.47, 1, 1.5eV and, also for the t\mu(1s) mean energy, 2.2eV . The variable x denotes the spacecoordinate measured from the H/T slab. The chemical cofinement formation rates are very high in the resonance energies. In order to obtain a converged solution we needed a large number of discritization points, the step sizes for x and time variables are, respectively, 2000 and 1015 . As more sequence, the balance equation reported at the bounary of the two layers in this conference, corresponds the our numerical results and would be applied for the space interval of 0+
