>From the conclusion of the article on 2nd order processes: The processes discussed explain the lack of the normally expected reaction products. ***It didn't look very convincing to me. This is all it says:
In the process formerly discussed [9] if the reaction takes place in solid material, in which instead of the emission of a photon, the nuclear energy is taken away by an electron of the environment (the metal), the Coulomb interaction induces a p + d → 3He nuclear transition. > >
