TSYPLAKOV The existence of ANRI absorption as a new effect arising from the interaction of a neutrino flux with a radioactive substance was first recorded from the radiation response and confirmed by a change in the heat flux. Prior to that, when studying the interaction of a neutrino flux with ordinary matter, opto and radiochemical methods of registration were used, working with a point, eventful manifestation of the process, in which it was unrealistic to expect the appearance of a mechanical component of the process. The large-scale increase in the neutrino capture cross section (about 30 orders of magnitude) in the ANRI effect makes the manifestation of the mechanical component (MS) in the interaction of a neutrino flux with radioisotopes inevitable and accessible for study by modern means, including monitoring the parameters of other processes. The proposed work is devoted to a brief review of modern observation and study of MS. Moreover, interest in the MS of an interacting neutrino flux when working with ANRI - the effect did not appear immediately, but over time it receives more and more attention: its role in measuring the parameters of the flux and locating the movement of space stations already requires research and accounting. This is what the new experiment is dedicated to, already with a classic precision balance. Keywords: ANRI – absorption (effect), the effect of a neutrino flux on radioisotopes, mechanical component (MS) of interaction, precision physical recording devices.
