### Abstract

We consider the possibility to estimate the energy of the neutrons coming, e.g., from piezonuclear effects (in electrolytic cells or in gas-metal system) using the counts of two detectors, assuming that the emission of neutrons follows a discharge-like behavior and therefore with a very short duration of the emission with respect to the period between two successive emissions. We show that using an ^{3}He counter as a ﬂat response detector with a constant intrinsic efficiency over a range from tens of keVs to few MeVs and a BF_{3} counter having in the same range an exponential intrinsic eﬁiciency, it is possible in principle to write down an equation connecting the ^{10}B microscopical cross section, for n - α reaction, and the counts of these two detectors. The ^{10}B microscopical cross section is related with the energy of the incident neutrons and a tabulate list of these values is available; therefore it can give a way to estimate this energy without using the spectroscopy method because of the very short duration of the emission.
