The heavy-ion reactions are characterized by a large number of channels, differing in various characteristics (angular distributions, mass distributions, kinetic energy, reaction cross sections, etc.). The major characteristics of two complex nuclei interaction processes is the mass distribution of reaction products. Therefore, one of the main features of the experiment is a direct measuring of the reaction products masses. This is directly achieved by measuring the masses of the forming nuclei. This paper describes the results of direct measuring of the reaction products masses using a precision time-of-flight technique. Tn this technique, microchannel plates (MCP) are used as the start and stop detectors. Using the 25 cm path length, time resolution of 240 ps was obtained, which made it possible to determine the nuclei masses with an accuracy of ±5 amu. The technique is applied in experiments to measure the heavy nuclei fission fragments characteristics (mass distribution and total kinetic energy), in reactions of complete and incomplete heavy ions fusion with nuclear targets.
