This is a continuation of a previous article (1) wherein analysis of experimental data yielded a new procedure for the calculation of k∞/ϵ. In this present paper corresponding values derived from conventional theoretical techniques are analyzed in a similar fashion. The results as presented amplify the discrepancy between cadmium ratio measurements and conventional resonance escape theory, thereby yielding a good illustration of the need for further theoretical as well as experimental work in this area. A suggestion for improving the accuracy of cadmium ratio measurements is also presented. It is shown that the previous general development can be utilized with slight modification to yield values for the resonance escape probability which are in essential agreement with values calculated by conventional techniques.
