At the Heavy Ion Research Facility in Lanzhou, scientists from the Institute of Modern Physics synthesized berkelium-235 and americium-231, marking significant advancements in nuclear physics. The synthesis involved bombarding a gold-197 target with an argon-40 beam, resulting in the successful observation of both isotopes through fusion-evaporation reactions and a gas-filled recoil separator.
The α-particle energies measured were 7632 keV for berkelium-235 and 7109 keV for americium-231, with the latter's half-life recorded at 75 seconds. This research highlights discrepancies between experimental and theoretical predictions, providing crucial data for future modeling of neutron-deficient actinide nuclei. The outcomes may influence how researchers approach the synthesis of similar isotopes moving forward.
