Abstract

New neutron-deficient isotopes,¹⁹⁷Rn,^197mRn, and²⁰⁰Fr have been produced and identified on the basis of genetic correlations in the¹⁶⁶Er(³⁶Ar,5n)¹⁹⁷Rn (E_lab=186, 200 MeV), and¹⁶⁹Tm(³⁶Ar,5n)²⁰⁰Fr (E_lab=186 MeV) reactions. The evaporation residues were separated from the beam by using a gas-filled recoil separator and implanted onto a position-sensitive solid-state detector. The α-decay energies (half-lives) of¹⁹⁷Rn,^197mRn and²⁰⁰Fr have been determined to be 7261±30 keV (51_-15⁺³⁵ ms), 7370±30 keV (18_-5⁺⁹ms), and 7500±3O keV, (570_-140⁺²⁷⁰ ms), respectively.
