Abstract
We study slow collective motion at finite thermal excitations on the basis of linear response theory applied to the locally harmonic approximation. The transport coefficients for average motion, friction \gamma, inertia M and the local stiffness C are computed along a fission path of Th-224 within a quasi-static picture. The inverse relaxation time \beta=\gamma/M and the effective damping rate \eta=\gamma/(2\sqrt{M|C|}) are found to increase with temperature, but do not change much with the collective variable. The values found for \eta and \beta as well as their behavior with temperature are in accord with experimental findings.
