Determination of the E2/ M1 mixing ratio of the 122-keV transition in the57Co-decay by nuclear orientation
Abstract
The E2/ M1 mixing ratio of the 122 keV γ-ray in the decay of57Co has been measured by a nuclear orientation experiment. In order to obtain a very accurate value, special care was taken to reduce all possible systematic errors. The final value is δ=-0.116±0.001, from which we deduced the transition probabilities B( M1)=0.0021±0.0001 μ{/N 2} and B( E2)=0.00267±0.00011 e 2 b 2.
