Fragment mass distribution has an asymmetric form. The thin structure corresponding to the fission product yields with masses of 104, 111, 126, 132 a. e. m. was observed. The gamma and alpha-spectromical researches of samples of fuel containing materials from 4th Unit of ChNPP were carried out. The isotopes ratio for Cs, Eu, Pu, Am and Cm were measured and fuel burning out were determined in the investigated samples. The divergence of theoretical estimations of lifelength were detected for all radionuclides upper Am-241. There was observed the systematic difference of fuel burning out value determined by Cs in comparison with other radionuclides. The causes of such differences are discussed. The measurement of isomeric yields ratios of photofission fragments was done, created in (g,f)- and (g,nf)reactions. Average angular momentums of heavy and light fission fragmentations of 237Np and 241Am nuclei have been defined, which were irradiated of bremmsstrahlung photons with end-point energy near 9.8 and 17 MeV. The effects of shells, odd and even-even effects have been observed in fissioned nuclei. The recent report was done.
