Highlights
•It shown the existence of an oversize of the average prompt neutron multiplicity as a function of the mass of fragments, measured by the 1V1E method, from the reaction 239Pu(nth,f) in the region of symmetric fission.
•It is found a correlation between the average prompt neutron multiplicity and the yield of the mass of fragments from the reaction 239Pu(nth,f).
•A high variation of the mass yield produces structures in the average prompt neutron multiplicity as a function of the mass of fragments.
