Abstract

Measurements were made of the fission-neutron multiplicity associated with eleven

{}^{239}{Pu}

resonances in the energy range from 20 to 100 eV. It has been found that the multiplicity values are strongly correlated with the spins of the individual resonances and that the average multiplicity for the

J = 0

group is 2.6% higher than for the

J = 1

group.
