Influence of Different Collective Coordinates on Spontaneous Fission Process in Fm Isotopes
A. Staszczak, Z. Lojewski
Abstract
We study the role of different collective degrees of freedom in spontaneous fission process of even--even Fm isotopes. To find a proper collective space we examine a reach collection of nuclear shape parameters \βλ\, with λ=2,3,4,5,6 and 8; as well as the paring degrees of freedom i.e. proton Δp and neutron Δn pairing gaps. On the basis of the multidimensional dynamic--programming method (MDPM) the optimal collective space \β2, β4, β6, Δp, Δn\ for Fm isotopes was found.
