A dynamic model of electron orbitals deformation (EODD) has been
developed making it possible to allow for dynamic effects of
outer electron shells screening on deuterons interactions.
Computer simulation based on the EODD model revealed that
deuterons in the palladium crystalline structure can approach
each other so that the distance between them can be less than
0.01
and gave estimated probability of such an approach.
Assuming deuterium be completely mobile in palladium, the
calculated rate of the fusion reaction at 300
is
10-10–10-12
per the D-D pair. This
value corresponds to the energy release of 1–100
per gram
of palladium β-deuteride and is in good agreement with
experimental data for excess heat measurements within an order of
magnitude.
