Abstract
The rate of nuclear fusion of d-d hydrogen isotopes in condensed matter is estimated. The authors calculate the probability for tunnelling in a model in which the interaction between two deuterons is described by tailoring a screened repulsive Yukawa potential with an harmonic potential. The fusion rate is established quantitatively as a function of the screening length Rs and the deuteron separation R0. It is shown that a fusion rate larger than 10-23 (s*deuteron pair)-1 can arise in a domain given approximately by R0+14.3Rs<or=2.9 in atomic units. The actual parameters for deuterium embedded in Pd lie far outside the range required for the above fusion rate.
