Alpha spectrometry applications with mass separated samples.

241 Am 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 241 Am samples using a small area passivated implanted planar silicon detector. We have also investigated the mass-based separation capability by developing a 238 Pu sample, present as a minor constituent in a 244 Pu standard, and performed subsequent radiometric counting. With this new sample development method, the 241 Am samples achieved the intrinsic energy resolution of the detector used for these measurements. There was no detectable trace of any other isotopes contained in the 238 Pu implant demonstrating the mass-based separation (or enhancement) attainable with this technique. [ABSTRACT FROM AUTHOR]
