The isotope 102254 was synthesized in the extracted beam of the OIYaI (United Institute of Nuclear Research) 150-cm cyclotron by means of the reaction Am243(N15, 4n) 102254. By recording the alpha disintegrations of the primary and daughter nuclei, it was shown that the half-life of this isotope is between 20 and 50 sec, while the energy of its emitted alpha particles is 8.10±0.05 MeV. These figures disagree with the literature data (T1/2=3 sec, Ecα=8.3 MeV).
