Title: Two-phonon octupole excitations in {sup 208}Pb: status and perspective

Abstract

Progress toward the identification of the two-phonon octupole multiplet in {sup 208}Pb is reviewed. Measurements with the {sup 208}Pb(n,n{sup '}{gamma}) reaction have permitted the characterization of a 0{sup +} state at 5241 keV, which decays by a cascade of E3 transitions. Additional measurements with this reaction have led to the identification of candidates for the 2{sup +} and 4{sup +} members of the quartet. Recent inelastic light-ion and neutron transfer reaction studies have led to further clarification of these candidates. In none of these studies or recent Coulomb excitation measurements has a reasonable candidate for the 6{sup +} excitation been identified. Quasiparticle-phonon model calculations of Ponomarev and von Neumann-Cosel seemingly account for all of the observed experimental data and add new information about the fragmentation of these excitations and the possible signatures for their decays.
