Separation of gram amounts of Am-241 from solutions of long-stored plutonium by displacement complexing chromatography is studied. A method for Pu after-recovery at the chromatographic refining stage is tested. Eight chromatographic cycl... OV Kharitonov,EA Chuveleva,VM Gelis,... - 《Radiochemistr...
The IAEA supplied and installed a 20 Ci 241Am–Be neutron irradiation facility at the National Nuclear Research Institute (NNRI) of the Ghana Atomic Energy Commission in 1977 for Neutron Activation Analyses (NAA) (Osae and Amoh, 1996, Osae and Akoto-Bamford, 1986, Tetteh, 1980). Fig. 1...
This reaction is still the best method for the production of pure 241Am. In post-World War II work at the University of Chicago, Cunningham isolated Am(OH)3 and measured the first absorption spectrum of the Am3+ aquo ion (Cunningham, 1948). By the 1950s, the major center for americium...
Local structure(Zr,Y,Am)O2 with 6 and 19 mol% Am were prepared by infiltration of americium in porous yttria-stabilised zirconia (YSZ) beads. Samples were sintered at 1600 °C in Ar/H2 to yield Am(III). By annealing them at 1000 °C in flowing air, the Am is oxidised to ...

Properties Americium, atomic number 95, was identified in 1944 at the University of Chicago by G.T. Seaborg, R.A. James, L.O. Morgan and A. Ghiorso in the form of isotope 241 Am ( t 1/2 = 432.6 years) as a product of the multiple neutron capture by 239 Pu followed by beta ...
