【Abstract】 A realistic calculation of the viscosity coefficients for ²³⁶U from ground equilibrium shape to saddle point is presented based on the linear response theory, in which the single particle spectra and wave function are provided by generalized Nilsson model. The dependence of viscosity coefficients γ_δ2δ2, γ_δ3δ3, γ_δ4δ4, γ_δ2δ3, γ_δ2δ4, γ_δ3δ4, on the collective variables δ₂, δ₃, δ₄ is studied at various values of the nuclear temperature with the smearing width Γ=0.1hω₀.更多还原
