Accurate measurements were performed of the photon emission probabilities following the α decay of 235U to 231Th. Sources of highly enriched 235U were characterised in terms of isotopic composition by mass spectrometry and their activities were stan

A wet chemical precipitation method to convert triuranium octoxide (U3O8), into uranium tetrafluoride (UF4) has been applied to determine the process yield. In this paper the wet chemical precipitation method is described in detail with a quantitativ

A sensitivity analysis for the new generation of fast reactors [Salvatores (2008)] has shown the importance of improved cross section data for several actinides. Among them, the240,242Pu(n,f) cross sections require an accuracy improvement to 1-3% and

Accurate neutron induced fission cross section of 240 Pu and 242 Pu are required in view of making nuclear technology safer and more efficient to meet the upcoming needs for the future generation of nuclear power plants (GEN-IV). The probability for

Multi-layer (235)UF4-(6)LiF-Au targets have been produced by vacuum deposition on thin polyimide foils with an areal density, measured by spectrophotometry, of about 33µgcm(-2). The foils were first covered with an Au-layer and then, with a second l

The methods of electrodeposition and “molecular plating” were studied for the production of uranium targets with an areal density up to 0.6 mg cm −2 on aluminium and up to 1.5 mg cm −2 on stainless steel backings from aqueous and organic elec

240Pu and 242Pu targets were prepared by the so-called “molecular plating” on an Al backing for cross-section measurements. The total activity of the actinide layer was determined by low-geometry alpha-particle counting. The atomic abundances of

For more than 30 years thin polyimide foils have been produced at IRMM by in-situ polymerisation. The procedure consists of three steps, all performed under ambient atmosphere: preparation of a polycondensate solution used to form foil by spreading o
