摘要:

Beams of D2O clusters with 10∼1000 eV per deuterium yield unexpectly high fusion rates. This is an energy range intermediate between hot and cold fusion, and as such may serve as a link bridgin the two regimes. We present a theoretical model capable of explaining apparently conflicting experimental results with beams of D2O clusters in which fusion rates higher than expected were observed, and beams of D clusters in which no fusion was observed. Calculated results indicate that total deuterium‐deuterium fusion rates can be enhanced by many orders of magnitude by the use of deuterium‐heavy atom cluster beams. A set of experimental test is proposed.

摘要:

The collapsing lattice model is developed based on the assumption that rapid material transitions in deuterated metals can induce a coherent release of elastic energy. (AIP)

摘要:

The anomalous nuclear phenomena observed in intermittent neutron emission and the extremely large branching ratio (105–108) of tritium to neutron production are associated with coherent phonon excitation and de‐excitation due to phase transitions in the low temperature PdDx deuteride. The non‐linearity, which comes from the many‐body effect of the surrounding atoms of deuteron and palladium in the phase transition, plays an important role in the intermittent neutron burst and in generating a larger fusion reaction rate than the fusion rate calculated by screened Coulomb potential, based on the mean field theory.

摘要:

An essentially new mechanism of eliminating the barrier in nuclear reactions of synthesis due to quantum‐mechanical averaging of paired and many‐body energy of interacting particles in microvoids in a solid is proposed. The results of calculations within the first order of perturbation theory indicate a complete ‘‘elimination’’ of the barrier in spherical microvoids of opticmal radiusRO&bartil;7.5 A˚. The same effect takes place in microslits with width LO&bartil;3 A˚. In structural inhomogeneities of both type with characteristic dimensions less than the optimal ones RO, LO, within the particles being condensed at the levels of quantized motion, as the concentration increases. An increasing pressure against the walls results in stretching the inhomogeneities up to the critical size, at which nonthreshold synthesis is realized. The characteristic time of the reaction realization in voids and slits has optimal size t∼10−5s.

摘要:

We study thed‐dnuclear reaction cross section in a multi channel approach. An extrapolation of the existing cross sections to zerod‐denergy by means of a dynamical three channel model is given. In particular the correct velocity behavior at low energies is obtained for the Debye screenedd‐dCoulomb interaction. We consider thed‐dthreshold resonances.
