Possible Results of a New Reaction

New Direction in Nuclear Physics Originated from the Neutron Activation Technique Application

“…. " [1]. Therefore, the only possible suggestion for "x" in our particular case would be the dineutron -2 0 n -a particle, consisting of the two bound neutrons.…”

“…Moreover, an application of this technique gave us a chance to observe a dineutron emission in the 159 Tb(n, 2 0 n) 158g Tb nuclear reaction according to Migdal's prediction [11]. 70 years after the theoretical foundation of the dineutron in [1], the evidence for a dineutron existence as a bonded particle was provided in [9]. This event opens up the new direction in Nuclear Physics: physics of the dineutron, or dineutron physics.…”

“…Then by "x" we could assume only two neutrons, but the threshold of the 159 Tb(n, 2n) 158g Tb nuclear reaction is 8.18 MeV [10] and about 1.3 MeV greater. Again, some ideas from [1] were very helpful since this paper was the pioneering one, in which an assumption about a possibility of a dineutron existence was reported for the first time: "The existence of the dineutron has been discussed but no evidence for their existence has been found. If they do exist, then important knowledge concerning the binding energies can be obtained .…”

“…Among others, neutron generators represent a very convenient instrument to irradiate samples of interest with neutrons of certain energy to further analyze the neutron-induced nuclear reaction products due to interaction of neutrons with nuclei in the irradiated sample. The idea to use the fusion reaction between the deuterium and the tritium as a source of high enough energy neutrons was published in [1] for the first time and then was widely disseminated. Therefore, neutron generators based on utilization of (d-d) or (d-t) nuclear reactions to generate neutrons and determine a composition of a sample or cross section of nuclear reactions provide a basis to carry out research or to develop some practical tasks.…”

Statistically significant observation of and cross-sections for a new nuclear reaction channel on 197Au with bound dineutron escape

“…Summary. -Results of this study shed some light on the process of reliable production of such unique particles as bound dineutrons, which were considered as nonexistent for a very long time since the first mentioning by Colby and Little in [8]. While the theoretical description of dineutron formation in the vicinity of a much heavier nucleus is for now not that much comprehensive, our statistically significant experimental results exceeding the 5σ criteria confirmed observation of a bound dineutron, what since now is not just hypothesized to exist, but is certainly existing.…”
