[0014] Preferably, the step of generating new H- ions comprises a step of ionizing the hydrogen which is in contact with the clusters.
[0015] In particular, the step of ionizing the hydrogen can comprise a step of continuously or variably or discontinuously supplying an energy vector to the hydrogen, in order to assist the molecular dissociation of hydrogen and to cause a further formation of H- ions in addition to the H- ions that are formed by interaction between molecular hydrogen H2 and a cluster surface. This process occurs by involving the valence electrons of the transition metal, whose transfer from the transition metal to hydrogen is assisted by supplying an amount of energy.
[0016] Such energy vector can comprise a ionizing radiation of various nature and frequency. In particular, such ionizing radiation can be selected from the group consisting of:
• a radiofrequency, in particular microwaves;
• a high intensity light radiation, as the one that can be obtained from concentrated spot power lamp or from a laser system;
• a light radiation;
• a UV - radiation;
• an X - radiation;
• an a - radiation;
• a β - radiation;
• a γ - radiation;
• a combination of such radiations.
[0017] In addition, or in alternative, the energy vector can comprise supplying particle beams . For example, such particle beams can comprise particles selected from the group consisting of:
• protons,
• hyperons,
• mesons,
• leptons;
• accelerated ions of any element, preferably metal ions;
• a combination of such particles.
[0018] A step can also be provided of prearranging a radioactive material proximate to said primary material.
