Determination of particle parameters in the k, l, and m shells in pb207

An angular-correlation setup was applied to measure the e-γ angular correlations involving the 570- and 1064-keV transitions in Pb207. The use of a Si(Li) semiconductor counter as an electron detector allowed the separation of the three K, L, and M conversion lines for both transitions. γ-γ angular...
