Internal conversion studies of the 2⁺ → 0⁺ transitions in some deformed even nuclei

Abstract

The K conversion coefficients of 2⁺ → 0⁺ transitions in some deformed even nuclei have been determined with the help of β-γ, χ-γ and γ-γ coincidence measurements. All possible uncertainties in these measurements have been minimised and properly evaluated. The a_K values for 2⁺ → 0⁺ transitions in Er¹⁶⁶, Yb¹⁷⁰, Hf¹⁷⁶, W¹⁸⁶, Os¹⁸⁶, Os¹⁸⁸ and Dy¹⁶⁰ are found to be 1.67, 1.31, 1.10, 0.55, 0.42, 0.34 and 1.52, respectively. These values are in agreement with the theoretical ones within an experimental error of about 6%. Large deviations of the order of 15 to 20% as reported by earlier workers are not observed.
