Abstract

Abstract 241Am has been deposited using a novel technique that employs a commercial inductively coupled plasma mass spectrometer. This work presents results of high-resolution alpha spectrometry on the 241Am samples using a small area passivated implanted planar silicon detector.We have also investigated the massbased separation capability by developing a 238Pu sample from a 244Pu standard and performing subsequent radiometric counting. With this new sample development method, the 241Am samples achieved the intrinsic energy resolution of the detector used for these measurements. There was no detectable trace of other plutonium isotopes contained in the standard from the 238Pu implant.
