| Abstract | Since our previous paper was written, we have learned of one new set of measurements that would have been included had we known of it: Gwin, Spencer and Ingle's measurement of the nu-prompt ratios of the four fissile materials with respect to /sup 252/Cf. Their recently published paper reports revised final results for /sup 233/U, /sup 235/U and /sup 239/Pu and includes a measurement on anti nu/sub p/(241)/anti nu/sub p/(252) that was not attempted previously. In some of the fitted results reported here, we have replaced their earlier 1978/1981 values by the final 1984 set. The replacement has appreciable effect on some of the parameters. Another revised value that we have used here is Axton's 1984 revision (3.7509 +- 0.0107) of his 1982 /sup 252/Cf anti nu/sub p/ value (3.744 +- 0.021). The effect of including the revised result is not appreciable. Thermal constants for /sup 233/U, /sup 235/U, /sup 239/Pu, and /sup 241/Pu are given. 11 references. (WHK) |
