This paper reports on the fission neutron spectra for spontaneous fission of {sup 240}Pu, {sup 238}Pu and {sup 242}Pu calculated using the spin-dependent Madland-Mix model. Experimental data on fission neutron spectra for these nuclei are scarce. The calculated differences in the three spectra are presented and compared with the available data, and some repercussions for plutonium assay work are discussed.
