Abstract
The α decay of the neutron-deficient At190 isotope was observed following the Rh103(Zr90,3n)At190 reaction at Argonne National Laboratory. The reaction products were separated from the beam using the Argonne Gas-Filled Analyzer and implanted into a double-sided Si strip detector. The spatial and temporal correlations between implanted nuclei and subsequent α decays towards the known daughter isotope Bi186 were used to identify and characterize At190 nuclei. Two possible decay scenarios are proposed for the At190→Bi186 decay.
