Statistical model calculations incorporating angular momentum dependent fission barriers were made to reproduce the observed cross section data of evaporation residues and fission. The observations can well be explained if the angular momentum dependence of fission barriers is taken into account in the competition process of fission and neutron evaporation in the decay of a compound nucleus except the observed trend of the width of the mass yield curve which could not be explained straightforwardly. 2- in low concentrations of bicarbonate.
Data suggest the possible presence of another species in the low carbonate and high pH region.
The thermodynamic calculation of the solubility is consistent with the present results on colloid formation. Independent extraction experiments, using DBM as extractant, were employed to validate the results. Possible reaction mechanisms have been suggested to account for the observed reaction stoichiometry. Modern chemical separation techniques enable high selectivity and high recovery. Optimizing steps lead to fraction concentrations high enough for direct filament loading in order to perform mass spectrometry measurements.
