results were obtained from Dr. S. Cohn by phone on April 2h, 1956. A follow-up letter from Dr. Cohn‘) expressed his idea that the discrepancy in the beta count probably lies in the conversion from c/m to d/fm. NRDL used Sr?0 ~ y90 as a standard in this case and for purposes of comparison, the HASL results were also standardized against sr90 ~ y90, It is felt that the use of KL as a standard allows the best approximation of the energy for mixed fission pro-~ ducts among the available long-lived isotopes(7), As an aid in evaluating these data, Figure 1 and Table 8 are included,
