摘要: Abstract The 350 keV l -forbidden transition in 207 Tl has been studied. mixing ratio δ γ (E2/M1) =+0.271 ± 0.004 deduced from a measurement of the plane polarization γ-rays; mixture preceding α-transition ( L = 3+5) also determined. K-shell internal conversion coefficient measured, α K 0.2041 0.0037. knowledge and used to study penetration effects conversion, giving two possible values, Λ ≈ 1 74 for factor defined by Church Weneser. analysis an additional angular correlation experiment, between α-rays electrons, yielding A 2 −0.010 0.015, rules out unambiguously larger value Λ.
