This study models deuteron fusion in metals like palladium. Conduction electrons screen Coulomb fields, enabling fusion at rates significantly lower than previously reported.

Area of Science:

  • Nuclear physics
  • Condensed matter physics
  • Materials science

Background:

  • Deuteron fusion in metals is a topic of interest for potential energy applications.
  • Previous studies have reported fusion rates that are difficult to reconcile with theoretical models.
  • Understanding the role of electron screening in fusion processes is crucial.

Purpose of the Study:

  • To investigate the feasibility of deuteron fusion in a metal lattice.
  • To model the effect of conduction electrons on Coulomb interactions between deuterons.
  • To compare theoretical fusion rates with experimental observations.

Main Methods:

  • A simple theoretical model of a metal containing deuterons was developed.
  • The model specifically considered palladium as a representative metal.

  • The impact of conduction electron screening on the Coulomb potential was calculated.

    • Main Results:

    • The screening effect of conduction electrons was found to be significant.
    • Deuteron pairs can fuse at calculated rates of approximately 10(-30) sec(-1).
    • These rates are seven orders of magnitude lower than those reported by Jones et al. (1989).

    Conclusions:

    • The theoretical model suggests that deuteron fusion in metals is possible.
    • Electron screening plays a critical role in modulating fusion rates.
    • The calculated fusion rates are substantially lower than previously experimentally suggested values, indicating a need for further investigation into experimental methodologies and theoretical underpinnings.
