Thanks for the information. I only had time to skim over the paper which left me with the understanding that the paper is a theoretical one and not the result of an experiment.
Did I fail to find the experimental evidence to support the hypothesis? If so, please help me find that reference. I hope that more vortex members submit facts such as this.

F., H-1521 Budapest, Hungary (Date textdate; Received textdate; Revised textdate; Accepted textdate; Published textdate) Abstract Nuclear processes in solid environment are investigated. It is shown that if a slow, quasi-free heavy particle of positive charge interacts with a ”free” electron of a metallic host, it can obtain such a great magnitude of momentum in its intermediate state that the probability of its nuclear reaction with an other positively charged, slow, heavy particle can significantly increase. It is also shown that if a quasi-free heavy particle of positive charge of intermediately low energy interacts with a heavy particle of positive charge of the solid host, it can obtain much greater momentum relative to the former case in the intermediate state and consequently, the probability of a nuclear reaction with a positively charged, heavy particle can even more increase. This mechanism opens the door to a great variety of nuclear processes which up till know are thought to have negligible rate at low energies. Low energy nuclear reactions allowed by the Coulomb assistance of heavy charged particles is partly overviewed. Nuclear pd and dd reactions are investigated numerically. It was found that the leading channel in all the discussed charged particle assisted dd reactions is the electron assisted d + d → 4He process.

SUMMARY It is found that, contrary to the commonly accepted opinion, in a solid metal surrounding nuclear reactions can happen between heavy, charged particles of like (positive) charge of low initial energy. It is recognized, that one of the participant particles of a nuclear reaction of low initial energy may pick up great momentum in a Coulomb scattering process on a free, third particle of the surroundings. The virtually acquired great momentum, that is determined by the energy of the reaction, can help to overcome the hindering Coulomb barrier and can highly increase the rate of the nuclear reaction even in cases when the rate would be otherwise negligible. It is found that the electron assisted d + d → 4He process has the leading rate. In the reactions discussed energetic charged particles are created, that can become (directly or after Coulomb collisions) the source of heavy charged particles of intermediately low (of about a few keV ) energy. These heavy particles can assist nuclear reactions too. It is worth mentioning that the shielding of the Coulomb potential has no effect on the mechanisms discussed. Our thoughts were motivated by our former theoretical findings [9] according to which the leading channel of the p + d → 3He reaction in solid environment is the so called solid state internal conversion process, an adapted version of ordinary internal conversion process [10]. 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. The processes discussed here can be considered as an alternative version of the solid state internal conversion process since it is thought that one party of the initial particles of the nuclear process takes part in Coulomb interaction with a charged particle of the solid material (e.g. of a metal). There may be many fields of physics where the traces of the proposed mechanism may have been previously appeared. It is not the aim of this work to give a systematic overview these fields. We only mention here two of them that are thought to be partly related or explained by the processes proposed. The first is the so called anomalous screening effect observed in low energy accelerator physics investigating astrophysical factors of nuclear reactions of low atomic numbers [11]. The other one is the family of low energy nuclear fusion processes. The physical background, discussed in the Introduction and in the first part of Section V., was questioned by the two decade old announcement [12] on excess heat generation due to nuclear fusion reaction of deuterons at deuterized Pd cathodes during electrolysis at near room temperature. The paper [12] initiated continuous experimental work whose results were summarized recently [13]. The mechanisms discussed here can explain some of the main problems raised in [13]. (a) The mechanisms proposed here make low energy fusion reactions and nuclear transmutations possible. (b) The processes discussed explain the lack of the normally expected reaction products.

Is anyone aware of proof that hot fusion types of reactions have been observed within the confines of a metal matrix that is not subject to very massive energy inputs?
