ANALYSIS OF HEAVY-ION-INDUCED DEUTERON-DEUTERON FUSION IN SOLIDS

When energetic heavy ions irradiate a deuteride titanium target, a num ber of recoil deuterium atoms are produced in the solid. The recoil de uterium atoms cause deuteron-deuteron (d-d) fusion reactions in solids . The probability of the d-d fusion reaction has been calculated for t he primary colliding deuterium atoms, as well as the collision cascade deuterium atoms. Based on calculated results, an experiment using a h eavy-ion accelerator was proposed to study d-d fusion in solids. The e nhancement effect on d-d fusion in solids is particularly interesting. The experimental parameters were as follows: The energy of the ion be am for the d-d fusion experiment was in the range from several to seve ral tens of mega-electron-volts for an experiment with an iodine ion b eam and a titanium target. The enhancement effect in the solid is eval uated by comparing the experimental results with the present calculate d results. The existence of the enhancement at low energies can be con firmed by measuring the depth profile of the fusion probabilities, Rep orted experimental data have been analyzed by the calculated results. The enhancement has not been found in the data.
