Abstract
Accelerator mass spectrometry has been applied for the first time to t he detection of Np-237. Sensitivity approaches 10(5) atoms. A first me asurement of the mobility of Np-237 in a marine environment is reporte d, and lends support to the prediction that neptunium should be substa ntially more mobile than plutonium. Measurements of backgrounds and tr ansmissions for plutonium and neptunium in different charge states are also reported. In addition, the relative negative ion formation proba bilities for the monoxide ions of Th, U, Np and Pu have been measured.
