Mixing strength in the two lowest 0- states in Pb208
Abstract
With a resolution of 3 keV, the two lowest 0- states in Pb208 are identified by measurements of the reaction Pb207(d,p) with the München Q3D magnetic spectrograph in the region Ex=5.2-5.7 MeV where the average level spacing is 6 keV. Precise relative spectroscopic factors are determined. Matrix elements of the residual interaction among one-particle one-hole configurations in a two-level scheme are derived for the two lowest 0- states in Pb208. The off-diagonal mixing strength is determined as 110±10(experimental)±15(systematic) keV. Measurements of the reaction Pb208(p,p') via isobaric analog resonances in Bi209 support the structure information obtained.
