    Abstract

    We investigate the importance of accounting for the transient time within the framework of the statistical approach (SA) for describing the fission process beginning from the quasistationary nuclear configuration. Two arguments are given in favor of the positive point of view on this problem. First, the average scission time is shown to be always larger than the inverse quasistationary fission rate by the value that is close to the transient time τr. Second, comparing the SA and the combined dynamical statistical approach (CDSA), we have found that suppressing the fission process for some delay time in the framework of the SA significantly reduces the amount of disagreement between the values of proper observables calculated using the SA and the CDSA.
