A new transuranium neutron-deficient isotope 235Am was produced by 35 MeV proton to bombard the rare radioactive 238Pu target The products were transported and collected by the He-jet system. The Am isotopes were separated and purified by radiochemtstry method and the γ-ray, X-ray and γ-X(γ) coincidence of the samples was measured The synthesis of 235 Am was definitely identified Its measured half-life is (15±5) mom.
A new transuranium neutron-deficient isotope 235 Am was produced by 35 MeV proton to bombard the rare radioactive 238Pu target The products were transported and collected by the He-jet system. The Am isotopes were separated and purified by radiochemtstry method and the gamma ray, X-ray and γ-X (γ) coincidence of the samples was measured in the synthesis of 235 Am was determined that it measured half-life is (15 ± 5) mom.
