Comment on “The use of CR-39 in Pd/D co-deposition experiments” by P.A. Mosier-Boss, S. Szpak, F.E. Gordon and L.P.G. Forsley Interpreting SPAWAR-type dominant pits

A recent claim [Eur. Phys. J. Appl. Phys. 40, 293 (2007)] demonstrating a nuclear process triggered by electrolysis is challenged. An analysis, based on relative diameters, is used to demonstrate that predominant pits could not possibly be attributed to alpha particles, or to less massive nuclear projectiles. This conclusion is supported not only by positive results from a replication experiment, but also by results from the experiment on which the original claim was based. While the numerous SPAWAR-type pits seem to be highly reproducible, their interpretation is not yet clear
