Abstract

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 lithium-6 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, re-examining the Jetter (n+⁶Li) and Post cycles (p+⁶Li), 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.
