The demonstration of what seems to be nuclear processes, by detecting apparent transmutation products and IMHO more importantly by finding a directional flux of neutrons coming out of the reaction zone is to me the most convincing thing of all. Some sort of contamination could in principle explain the non-palladium elements, but no contamination phenomena could possibly explain the neutrons, particularly since they showed a clear directional orientation.
I wish professor Biberian had shown SEM-EDX data of the sample surface before irradiation by the 5mW laser. Also he didn't state whether the "hot spot" was in region of maximum laser flux; it would have been nice if he had been able to show the distribution of regions of apparent nuclear activity in relation to the location of the laser beam spot. This is seemingly left to our imagination.
To me, the CR39 results showing neutron damage tracks has always been the most convincing evidence that something of a nuclear nature is going on. SPAWAR has seen abundant CR39 evidence in their co-deposition experiments, which they have made public in several venues and by publication.
This seems to be the experiment replicated.

Abstract
In a continuation of the research started in the late 1990s at the University of Lecce, and then repeated in 2004, recently in the second half of 2014 in the A.R.G.A.L. lab., it was decided to thoroughly investigate the LENR anomalies of Pd–H2 system (in gaseous environment), having as reference the preparation techniques and surface analysis used in the microelectronics industry, to demonstrate convincingly that material contamination was not affecting the transmutation findings.
As previously, the activation of the anomalies occurred during irradiation by low power lasers (633 nm, 1 mW, or 403 nm, 3 mW) on 250 nm thick palladium layers deposited by high vacuum e-beam evaporation on silicon oxide substrates, and with 30 nm of Cr as adhesion layer. In summary we did the following: in a stainless steel chamber filled with hydrogen, through a glass viewport, the sample surface was irradiated for two weeks and then accurately inspected in a SEM equipped with an EDX microprobe. A reference sample was also accurately analyzed before irradiation. c ⃝ 2016 ISCMNS. All rights reserved. ISSN 2227-312
. Conclusions
The experiments cited as background indicate the presence of transmutations similar to those shown in these replication experiments described above. Often the transmutation findings were associated with other LENR anomalies, such as emission of neutrons and excess heat generation. Induced oscillations in the material, by ultrasound, radiofrequency, or laser radiation, sometimes appears essential for the occurrence of the anomalies. Since some elements attributable to transmutations can easily come from environmental contamination (Na, Si, Al, Mg, Ca), we plan to replicate controls on the samples with accurate SEM analysis before the laser treatment in the reactor. Finally, because almost all the experimental evidence reported, new and old, points to transmutation of the reacting material to lighter elements, a deeper investigation of possible fission reactions of the material submitted to the described tests is strongly suggested.
