Abstract

A systematic experimental study on muon-catalyzed fusion was conducted using a series of solid deuterium and tritium mixtures. A variety of conditions were investigated, i.e., tritium concentrations from 20% to 70%, and temperatures from 5 to 16 K. With decreasing temperature, we observed an unexpected decrease in the muon cycling rate ([Formula presented]) and an increase in the muon loss probability ([Formula presented]). The origins of these observed changes were interpreted by the temperature-dependence in the [Formula presented] formation process for [Formula presented] and that in the muon reactivation process after muon-to-[Formula presented] sticking for [Formula presented].
