Abstract
Investigation of optimum conditions in muon catalyzed fusion (μCF) is very important for increasing the fusion yield. Usually a μCF target is considered in the form of a mixture of liquid, gas or solid layers. For this purpose a 3- solid layer of hydrogen isotopes, HT/D2/DT has been suggested by the other researchers. In this paper, this suggestion is investigated, and it is shown that the proposed 3-layer, decreases the fusion yield. Then, a multilayer of the HT and D2 in a sphericalarrangement is proposed to increase the fusion yield, and its conditions are studied. It is shown that in the proposed multi- layer, the fusion yield increases about 30 percent in comparison with one DT layer, while, the tritium concentration should be rare up to Ct=0.01. For this purpose, production of µt atoms beam by interring muons  into a HT solid layer is investigated. The Ramsauer-Townsend effect and transfer of muon from µp to µt atoms are important parameters in this investigation.
