Abstract: | Summary A general scheme is proposed for the interpretation of the phenomena involving low-energy hydrogen-isotope fusion. This scheme
is especially developed for the interpretation of the fusion rate observed after the impact of heavy-water clusters (D2O)
n
, 25≲n≲1350, onto targets of titanium deuteride TiD. It is shown that 1) the impinging energy of large clusters or molecules is
equiparted among a lot of target atoms which are brought in collective motion; 2) data can conveniently be represented in
an Arrhenius plot; 3) this plot suggests that fusion is a thermally activated process from a metastable precursor; 4) the
activation energy for the precursor formation isE
*≃2E
0 (E
0 being the electron binding energy in the hydrogen atom), and 5) the activated precursor can reasonably be identified with
the metastable binuclear heliumlike (D+D+)2e− atom. |
