Properties of Radioactive Decay of the New Nucleus 227Pu
A new isotope 227Pu was discovered by complete fusion reactions 26Mg + 204Pb and 26Mg + 206Pb. The experiment was carried out at the GRAND separator of the SHE Factory at Flerov Laboratory of Nuclear Reactions, JINR. For the nucleus 227Pu, an α-particle energy of Eα = 8156 ± 26 keV and a half-life of Т1/2 = $$2.2_{{ - 0.3}}^{{ + 0.5}}$$ s were measured. A single event with Eα = 8754 ± 24 keV and an estimated lower limit half-life of 1 ms from the measured lifetime, which is probably attributed to the new isotope 226Pu, was identified by chain with 222U.
