[en] The ²⁰⁶Pb(p, d)²⁰⁵Pb reaction has been studied at 35 MeV. The angular distributions for this reaction were measured relative to the angular distributions for the ²⁰⁸Pb(p, d)²⁰⁷Pb reaction to the single-neutron-hole states in ²⁰⁷Pb and relative spectroscopic factors are reported. The non-energy-weighted sum rule is used to determine the orbit occupancies of the ²⁰⁶Pb target. These orbit occupancies are combined with other experimental results to determine the ground state wave function of ²⁰⁶Pb. The Bansal-French energy-weighted sum rule is used to deduce some properties of the neutron-neutron effective interaction. Detailed comparison between experimental spectroscopic factors and predictions of recent nuclear model calculations is made
