Some New Aspects of Bimodal Fission in 258Fm Isotope
A. Staszczak, Z. Lojewski
Abstract
Using the multidimensional dynamic--programming method (MDPM) in the four--dimensional deformation space \βλ\ with λ=2, 4, 35 and 6 we were able to study evolution of the action integral for the fissioning nucleus 258Fm. We found the second minimum on the cross--section of the action integral for β2 ≈ 1 , what we interpret as the dynamical evidence of the bimodal fission in this heavy Fm isotope.
