We recently conducted electrochemical co-deposition experiments inspired by the SPAWAR studies, in which Pd is co-deposited onto an Au substrate in heavy water. This process results in a highly fractal Pd deposit with vacancies, facilitating rapid deuterium loading. Both high D/Pd loading and vacancy formation are considered essential for initiating LENR. A notable observation in our experiments is the emission of MeV charged particles, a phenomenon indicative of LENR that remains unexplained by conventional theories. Given the low production rate of charged particles, CR-39 track detectors are particularly well-suited for long-duration measurements in these low-count-rate conditions. Our results display track patterns on CR-39 similar to those previously reported in SPAWAR studies. Additionally, we observed triple tracks on the CR-39 detector, providing evidence of energetic neutron emission. These tracks are consistent with C-12 disintegration caused by neutrons with energies exceeding ~9 MeV.
Reproducibility has been a persistent challenge in LENR research, with the need for robust and accessible "lab rat" experiments. Our findings demonstrate that the SPAWAR co-deposition experiment offers a reproducible platform for investigating LENR phenomena, contributing to the ongoing exploration of anomalous nuclear effects. Further investigation of the properties of Pd co-deposits and the establishment of clearer correlations between their physical characteristics and observed LENR signatures will advance the fundamental understanding of LENR and create opportunities for potential applications.
