Description
Summary:Accelerator mass spectrometry has been applied for the first time to the detection of 237Np. Sensitivity approaches 105 atoms. A first measurement of the mobility of 237Np in a marine environment is reported, and lends support to the prediction that neptunium should be substantially more mobile than plutonium. Measurements of backgrounds and transmissions for plutonium and neptunium in different charge states are also reported. In addition, the relative negative ion formation probabilities for the monoxide ions of Th, U, Np and Pu have been measured.
