| Abstract: | A nuclear track emulsion (NTE) is exposed to 60 MeV 8He nuclei. Measurements of decays of 8He nuclei stopped in NTE allow one to evaluate possibilities of α-spectrometry. Thermal drift of 8He atoms is observed. Knowledge of the energy and emission angles of α-particles allows one to derive the energy distribution of α-decays Q2α . The presence of a “tail” of large values Q2α is established. |
