Description

To study presence and influence of deformed nuclear shells we measured mass and energy distributions of fission fragments of 240Pu* compound nucleus in 236U(α,f) reaction at incident alpha particle energy of 29 MeV which is at coulomb barrier for this reaction. Measurements were carried out with 2E method at U-150M accelerator at the Institute of Nuclear Physics, Almaty city, Kazakhstan. Acquired mass and energy distributions were decomposed into yield of separate fission modes with sensitive decomposition method taking into account deformed nuclear shells. The results show influence of deformed nuclear shells Z52, N84, N88 on mass and energy distributions of fission fragments.
