Anomalous electron intensity ratio of the E0 internal conversion in the transitions of 154Gd

Abstract Relative probabilities of the E0 internal conversion for the K, L, M and N + O shells in the transitions of 154 Gd have been studied in detail with the use of special electron measuring techniques. They were compared with the theoretically predicted values. It turned out that the internal conversion is successively hindered from the outer to the inner shells on the assumption that the conversion for the outer shells is normal.
