Summary

Measurements using the manganese bath technique are central to the discrepancy that has existed between measured values of nu-bar for 252Cf. Manganese bath measurements of nu-bar belong to the lower group of values, while the eta measurements are consistent with the higher nu-bar values. A three-part study was performed to see if the discrepancy could be explained by differences in manganese bath techniques: (1) A 252Cf source previously calibrated by De Volpi was calibrated in the MTR manganese bath; (2) The recommendations made by De Volpi for altering the MTR eta values were carefully considered; and (3) The results of the Monte Carlo calculation of the MTR experiments, carried out at Bettis Atomic Power Laboratory, were examined in detail. The study produced insignificant changes in the eta values. (6 tables) (auth)
