摘要：

The low-lying level structure of the neutron-deficient isotope Rn-202 has been studied for the first time, using the Ta-181(Al-27,6n) and Pt-192(O-16,6n) reactions. Gamma-ray transitions between excited states in Rn-202 were identified by mass tagging using a recoil mass separator, the Argonne Fragment Mass Analyzer, and by observation of coincident x rays. Transitions in Rn-203 were also identified. The level scheme deduced from these data is consistent with the systematics of light radon isotopes below the N = 126 shell closure and with theoretical calculations indicating that the ground-state shape should not be strongly deformed at N = 116.
