The electron assisted low energy $dd$ reactions in deuterized metals are investigated. It is shown that if a metal is irradiated with slow, free deuterons then the $e+d+d\rightarrow e^{\prime }+p+t$ and $e+d+d\rightarrow e^{\prime }+n+$…

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 ($^6$LiD) with neutrons. Modern-day…

Recently we showed that the nuclear transmutation rates are largely overestimated in the Widom-Larsen theory of the so called `Low Energy Nuclear Reactions'. Here we show that unbound plasma electrons are even less likely to initiate…
