Some recent experiments in the HELIS facility show increased neutron production ~ 2.5 MeVs ?
for 25 kev input.
.of course 25 kev is equivalent to 29 million K in a hot collision environment
which is not LENR.. at least not in the same league as 100C ( Fleischmann and Pons) and 300C (Mizuno... Takahashi...etc)
. The DD reaction yield values calculated for given experimental conditions are also indicated. Figure 1 shows
that the experimental DD reaction yields obtained on the targets significantly exceed the calculated
values. , the experimental yields are, respectively, 2 and 4 times higher than the calculated values(from known cross sections)
under irradiation with the deuterium ions beam.
These calculated values wre based on known cross sections for these two reactions..
d+d→p(3 MeV)+T(1 MeV))
d+d→n(2.45 MeV)+3He(0.8 MeV)
Although these results are interesting .. they may not be relevant to LENR at much lower temperatures.
