1996KoZZ, 1996Gu11, 1997Sh21, 1999Ya13: Activity produced by 238Pu(p,4n), E=35 MeV. Chemically separated and assigned to 235Am on the basis of detected Pu K| x ray, as well as Np K| x ray and a 49.1-keV γ ray from 235Pu (daughter nucleus of 235Am) electron-capture decay. Activity was transported using a He-jet recoil technique. Measured γ rays, Xγ coin. Deduced T1/2.
1999SaZT: Activity produced by 235U(6Li,6n), E=60 MeV. Mass-separated and assigned to 235Am on the basis of detected Pu K| x ray. Measured γ rays in singles, Xγ coin, and γγ coin experiments. No γ rays coincident with Pu K| x ray were detected. Deduced T1/2.
2000SaZO: Activity produced by 233U(6Li,4n), E=45.5 MeV. Mass-separated and assigned to 235Am. Measured γ rays, Pu K| x ray, Np K| x ray, α particles (Eα). Detectors: Si-pin photodiodes for α particles; High-purity Ge for γ rays. Deduced half-life, Iα/ε branching ratio.
2004As12, 2004Sa05: Activity produced by 233U(6Li,4n), E=34-42 MeV. Separated ions implanted in a Si α detector, two Ge detectors used for γ-rays. Measured: α, γ, αγ, γγ, Np K| x ray, and Pu K| x ray, L| x ray, studied 235Am ε and α decay.
