Abstract
Possibility of nuclear reactions in solid state is intriguing for two reasons:
It provides a means of studying nuclear processes in conditions that are much different from traditional plasma-filled reactors or particle accelerators;
it dramatically lowers the cost and complexity of the experimental setups by eliminating the highly capital intensive components such as plasma/vacuum systems and particle accelerators.
In this article we report the observation of neutron emission coincident with acoustic cavitation of deuterated titanium powder suspended in mineral oil. The resulting neutron emission was detected using an assembly of 3He proportional neutron counters. The peak neutron count rate was in excess of 6500 CPM, more than 10,000 times in excess of background. The observed neutron emission was coincident with the application of acoustic influence.
The neutrons were present only when secondary acoustic waves originating from the complex bubble interactions inside the reactor constructively interfered resulting in massive, sharp pressure peaks on the order of a few thousand psi. We were able to sustain the neutron production for several hours and repeated the experiment multiple times under various conditions. We hypothesise that the observed neutrons originate from nuclear fusion of deuterium ions dissolved in titanium lattice due to the mechanical action of the impinging cavitation jets, although other processes (such as spallation) still need to be ruled out.
Kudos are in order to Max for getting this published in Nature Sci Reps, and also for publishing it with open access.
This is a Titanium/D based system. It has been shown (reported at ICCF-17 by a Texas University PhD) that if you hit deuterated Ti, it produces neutrons. However, immediately after this paper was published, Alexander Shishkin sent me this.
"Спасибо, но это не нейтроны. Сигнал от регистрации нейтрона на рис 2 отличается от сигнала на рис 8.Такие же сигналы регистрировал Леонид Уруцкоев при взрыве титановой фольги. Он назвал их «фальшивыми» нейтронами."
Which translated says:
"Thank you, but these are not neutrons. The signal from the neutron registration in Fig 2 is different from the signal in Fig 8. The same signals were registered by Leonid Urutskoev during the explosion of titanium foil. He called them "fake" neutrons."
To give perspective, Alexander Shishkin is the expert in Russia on determining with neutron detectors the difference between the two types of signals.
