Abstract

A method is presented for computing the mean number of secondary fission neutrons ¯v from the fission-fragment mass distribution curves. The error of the method is estimated. It is shown that in those cases in which the fragment mass distribution curves are carefully studied, ¯v can be determined with satisfactory accuracy by this method. The value of ¯v is computed for fission in Th232, U233, U235, U238, Pu239, Am241 and Cf252. The results are discussed and compared with results obtained by other methods. The partial values ¯v m are computed for thermal-neutron fission of U233 and U235.
