Corrections of the large liquid scintillator measurements by Boldeman et al. and Soleilhac et al. for the delayed gamma rays from fission have produced consistent values for the average number of prompt neutrons (ny-prompt) produced in the fission of 235 U. The absolute value of ny-prompt for thermal-neutron fission is 2.389 plus/minus 0.009, and the energy dependence is approximately linear. The data do not support the existence of fine structure between 200 and 600 keV nor the broad step-like structural dependence found in recent evalutions. However, there is the suggestion of a slight flattening of the curve representing the data between 250 and 600 deV.
