Abstract

The low-lying level structure of the neutron-deficient isotope ${}^{202}{Rn}$ has been studied for the first time, using the ${}^{181}{Ta}$ $(^{27}$ Al,6n) and ${}^{192}{Pt}$ $(^{16}$ O,6n) reactions. Gamma-ray transitions between excited states in ${}^{202}{Rn}$ were identified by mass tagging using a recoil mass separator, the Argonne Fragment Mass Analyzer, and by observation of coincident x rays. Transitions in ${}^{203}{Rn}$ 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.
