Abstract  

The applicability of the k0 standardization concept in ENAA has been investigated by comparing for 32 isotopes the experimentally determined ke, 0-values with those calculated from well-known k0 and Q0=l00 factors. It is concluded that the k-comparator method can be extended and applied in general to epicadmium (n, γ) activation analysis. Attention is also paid to some specific problems, such as the deviation from the ideal epithermal neutron flux distribution, the uncertainty in the effective Cd cut-off energy for the Cd-covers used, and the cadmium epithermal neutron transmission factor for which a literature survey is presented.
