Abstract

The reaction ${}^{208}{Pb}$ ( ${}^{16}O$ , ${}^{18}O$ ) ${}^{206}{Pb}$ has been measured at incident energies of 69, 71, and 73 MeV. Calculations free of optical-potential ambiguities and utilizing spectroscopic information derived from extensive sub-Coulomb single-neutron-transfer experiments show that, even at these low energies, the sequential transfer of two neutrons is the dominant process.
