Equal Charge Displacement Rule in Fission Product Poisoning

The equal charge displacement rule has been used for estimating yields of some important fission products. The results are not appreciably different from previous estimates but the present method increases the reliability of the values. Using recent yield values, thermal and resonance effects of gross fission products have been calculated and compared with measured effects in an irradiation experiment by Gunst, McGarry, and Scoville as well as with previously calculated values.
