The test experiment allows radioactive 8He nuclei to be independently identified by their decays as they stopped in the emulsion, the possibility of carrying out the alpha spectrometry of these decays to be estimated, and the drift of thermalized 8He atoms in matter to be observed for the first time. The experiment proved the high purity of the beam of radioactive nuclei formed at the ACCULINNA facility with an energy ranging from 10 to 30 MeV/nucleon.
