Abstract

A rapid gas-jet system was used for preparation ofβ −-samples of139mCe and141mNd. Conversion electrons and photons were detected simultaneously with absolutely calibrated detectors. Conversion coefficientsα K = 0.0732±0.0023 andα K=0.0824±0.0029, conversion ratiosK/L+...= 4.68±0.20 andK/L+...=4.58±0.23 were measured for139mCe, and141mNd, respectively. The calculated M4 values of Hager and Seltzer, and Dragoun et al. were confirmed within the experimental accuracy.
