Abstract

Evidence for collective behavior in the high-spin region of lead nuclei is provided by the observation of two collective structures in Pb197. One of these bands is interpreted as an oblate collective structure built on oblate proton and possibly neutron states. A second more irregular band is suggested to be most likely a triaxial rotational band. Neutron and proton configurations for these bands are suggested from the results of quasiparticle Routhians and total Routhians surface calculations. A partial level scheme up to I 69/2 and Ex 8 MeV is presented.
