Abstract: Gamma-ray spectra from<superscript>239</superscript>Pu(n,f) reaction were measured with the gamma spectrometer on the pulsed reactor IBR-30. The fast 19-section ionization chamber with 1.6 g of<superscript>239</superscript>Pu targets was used. The fission gamma-rays within the 32 ns time window were measured using a Ge(Li) detector. Based on the measured gamma-ray spectrum in the (0.1–1.8) MeV interval, the total number of emitted?-quanta-multiplicity <N<subscript>?</subscript><superscript>tot</superscript>> and total energy of ?-quanta per fission event, <E<subscript>?</subscript><superscript>tot</superscript>>, were calculated. The results were 7.0±0.6?/fission and 6.8±0.5 MeV/fission respectively.
