Sammanfattning

The α decay of the neutron-deficient ¹⁹⁰At isotope was observed following the ¹⁰³Rh(⁹⁰Zr,3n)¹⁹⁰At 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 ¹⁸⁶Bi were used to identify and characterize ¹⁹⁰At nuclei. Two possible decay scenarios are proposed for the ¹⁹⁰At→¹⁸⁶Bi decay.
