It is theoretically shown that an attractive effective potential isgenerated via optical phonon exchange between two quasi-free, differentparticles in deuterated Pd which, in turn, enhances the probability oftheir nuclear fusion reaction. Mechanisms, thatmay be responsible for extra heat production and nuclear isomer formation,are also discussed. Creation of 4He pairs dueto the significantly increased probability of the p + 7Li $\rightarrow$ 24He + 17.35 MeV and d + 6Li $\rightarrow$ 24He + 22.37 MeVnuclear reactions is predicted. Some of the basic questions of fusion reactions insolids seem to be successfully explained.
