Deuteron-deuteron (DD) fusion reactions can be investigated at extremely low energies due to the relatively low Coulomb barrier that can be further reduced by the surrounding electrons in metallic targets. Recently, instead of an…

The semi-inclusive deep inelastic scattering of electrons off the deuteron ($^2H \equiv D$) and $^3He$ with detection of slow protons and deuterons, respectively, i.e. the processes $D(e,e'p)X$ and $^3He(e,e'D)X$, are calculated within the…
