| Abstract | A new proton-unbound isotope 204Ac was produced in the fusion-evaporation reaction 169Tm(40Ca, 5n)204Ac and identified via the recoil-alpha correlation at the gas-filled recoiled separators SHANS2 and SHANS. The excitation function for producing 204Ac was measured and the optimal beam energy was evaluated to be 212 MeV. Nineteen ER -alpha 1 -alpha 2 -alpha 3 decay chains were observed for this isotope. Based on these chains, the alpha-particle energy and half-life of 204Ac were determined to be 7948(15) keV and 7.4+2.2 -1.4 ms, respectively. Both are consistent with the theoretical prediction. The reduced alpha-decay width was deduced to be 49+10-15 keV, which indicates a favored alpha decay for 204Ac. In addition, more precise decay properties of E alpha = 7883(15) keV and T1/2 = 7.7+2.7-1.6 ms were obtained for 205Ac. (c) 2022 The Authors. Published by Elsevier B.V.
