摘要: The internal conversion process of the 208 keV retarded E1 transition in 177Hf is studied by measuring electron-gamma and gamma-gamma directional correlations 208-113 cascade. result for ratio between correlation coefficients, A2(K)/A2(γ) = -1.66±0.04, agreement with theoretical value a pure transistion, -1.68. nuclear current penetration parameter, λ1= -0.15±0.25, agrees that calculated from effect 321 use branching rules rotational model.
