“…When this value is exceeded, a study of the isotopes responsible for the increased activity must be carried out. Among the different identification techniques, α spectrometry is one of the most frequently used . Recently, inductively coupled plasma-mass spectroscopy (ICPMS) , has also been utilized as a reliable, although very expensive technique for this purpose.…”

Development of an Automatic Method for Americium and Plutonium Separation and Preconcentration Using an Multisyringe Flow Injection Analysis-Multipumping Flow System

A new procedure for automatic separation and preconcentration of 241Am and 239+240Pu from interfering matrixes using transuranide (TRU)-resin is proposed. Combination of the multisyringe flow injection analysis and multipumping flow system techniques with the TRU-resin allows carrying out the sampling treatment and separation in a short time using large sample volumes. Americium is eluted from the column with 4 mol L(-1) hydrochloric acid, and then plutonium is separated via on-column Pu(IV) reduction to Pu(III) with titanium(III) chloride. The corresponding alpha activities are measured off-line, with a relative standard deviation of 3% and a lower limit of detection of 0.004 Bq mL(-1), by using a multiplanchet low-background proportional counter.

This evaluation presents a study (2010Hu02) of the 2 3 7 Np( 1 1 6 Sn, 1 1 8 Snγ ) reaction where the ground state rotational band 5/2[642] was observed up to Jπ =(53/2+).
