An innovative approach for studying transient effects in nuclear fission is proposed. Fragmentation of radioactive actinides is employed to prepare fissile nuclei in well-defined initial conditions, and the fission-fragment nuclear charge distribution is used to establish a clock for the dynamical evolution of the system. Based on a so-far un-reached large number of fissioning systems, the study demonstrates the undeniable manifestation of transient effects at high excitation energy and addresses the question about the influence of initial deformation.
