Jetter and Post Nuclear Fusion Cycles: New Fire to an Old Idea

New calculations of the time evolution and isotopic composition for a network of nuclear reactions breathe new life into an old idea in nuclear fusion, burning solid room-temperature ⁶Li deuteride (⁶LiD) with neutrons. Modern-day compilations of nuclear cross sections are nowadays available, and we use them to predict the full course of networks of thermonuclear reactions, reexamining the Jetter (n + ⁶Li) and Post cycles (p + ⁶Li), named after U. Jetter and R. F. Post, that offer great prospects for energy production in devices not based on plasma confinement. We present ideal calculations, i.e. not including the energy loss due to the stopping power, and more realistic calculations that include the Bethe-Bloch formula. We find that a significant amount of energy can, in principle, be generated.
