Search for neutrons from deuterium-deuterium nuclear reactions in electrochemically charged palladium

Abstract

We report on a search for neutrons from dd fusion in Pd rods loaded electrochemically with deuterium. In a four-week measurement we observe <0.007 n/(sec g) Pd, compared to 2.6\ifmmode\times\else\texttimes\fi{}${10}^{3}$ n/(sec g) Pd, claimed recently by Pons, Fleischmann, and Hawkins. Our result implies 2.2\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}24}$ (ddn) fusions/[(dd pair) sec], as compared to \ensuremath{\sim}${10}^{\mathrm{\ensuremath{-}}23}$ (ddn) fusions/[(dd pair) sec] observed by Jones et al. in a Ti electrode.
