Abstract
We have compared the results of dynamical modeling of the fission process with predictions of the Kramers formulas. For the case of large dissipation, there are two of them: the integral rate RI and its approximation RO. As the ratio of the fission barrier height Bf to the temperature T reaches 4, any analytical rate is expected to agree with the dynamical quasistationary rate RD within 2%. The latter has been obtained using numerical modeling with six different potentials. It has been found that the difference between RO and RD sometimes exceeds 20%. The features of the potentials used that are responsible for this disagreement are identified and studied. It is demonstrated that it is R I, not RO, that meets this expectation regardless of the potential used.
