This paper explains the _evidence_ of excess heat and helium production in "cold fusion" type experiments in terms of weak interactions and ultra low momentum neutrons.
The abstract and the concluding paragraph are below. I downloaded the entire paper from Steve Kirvit's New Energy Times. The paper also mentions that laser light could be used but I do not see any references to the experiments that have already been done with laser light.

Ultra low momentum neutron catalyzed nuclear reactions in metallic hydride system surfaces are discussed.Weak interaction catalysis initially occurs when neutrons (along with neutrinos)are produced from the protons that capture ³heavy ²electrons.Surface electron masses are shifted upwards by localized condensed matter electromagnetic fields.Condensed matter quantum electrodynamic processes may also shift the densities of final states,allowing an appreciable production of extremely low momentum neutrons, which are thereby efficiently absorbed by nearby nuclei.No Coulomb barriers exist for the weak interaction neutron production or other resulting catalytic processes. <snip> In summary, weak interactions can produce neutrons and neutrinos via the capture by protons of heavy electrons. The collective motions of the surface metallic hydride protons produce the oscillating electric fields that renormalize the electron self energy, adding significantly to the effective mass. There is no Coulomb barrier obstruction to the resulting neutron catalyzed nuclear reactions. The final products (A,Z) X in some reaction chains may have fairly high A .The above examples show that final products such as (4,2) He do not necessarily constitute evidence for the direct fusion D +D --> (4,2) He. Direct fusion requires tunnelling through a high Coulomb barrier. By contrast, there are no such barriers to weak interactions and ultra low momentum neutron catalysis. Final products such as (4,2) He and /or (3,2) He and /or (3,1) H may be detected.
