The prompt neutron emission multiplicity distribution P/sub v/ and its average value (i.e., nubar) have been determined at the standard neutron energy of 0.0253 eV for the neutron-induced fission of the four fissile nuclides /sup 233,235/U and /sup 239,241/Pu. Revised values of have been obtained by reevaluating experiments measured at 2200 m/s relative to the from the spontaneous fission of /sup 252/Cf. These revised values of have been used to renormalize the measured P/sub v/ values. The revised values of are all --0.25 to 0.5% smaller than the corresponding values of ENDF/B-V.
