Samples of superpure Pu-239 and Pu-241 were obtained by electromagnetic separation with the S-2 separator, and the determination of the periods of spontaneous fission of these isotopes was possible. The isotope composition of the plutonium samples was determined with mass spectrometry. Pu-238 concentration was also measured, with alpha spectrometry. Targets of the plutonium isotopes were prepared by electrodeposition from isopropyl alcohol solutions onto metal substrates of platinum and nickel. The fission fragments were recorded with solid-state track detectors of synthetic mica TU-41-955-71. The half lives of spontaneous fission of Pu-239 and Pu-241 were calculated. The isotope composition of isotopes Pu-240 and Pu-242 are also presented.
