In the domain of reactions, its time-dependent version (TDGCM) has been developed and applied to predict the dynamics of heavy-ion collisions or fission where the collective fluctuations play an. 10, 118 (1974)], the time-dependent generator coordinate method (TDGCM) is. (DOLSHIP), is one of the major players in the Philippineship manning industry. In this paper, we present the version 2. Dans la seconde étape, la dynamique est décrite dans cet espace de configurations en utilisant la méthode de la coordonnée génératrice dépendante du temps (TDGCM). To simulate the splitting process of the nascent fragments beyond scission, we also introduce a density constraint into the new CDFT framework. In the TDGCM+GOA, fission is assumed as adiabatic process since the typical time for the motion of individual nucle-ons inside the fission nucleus (roughly 10−22 s) is roughly ten times smaller than the time scale of the system’s col-lective deformation (10−21 s) [29]. In the TDGCM, the nuclear wave function is described as a superposition of generator states parameterized by a vector of collective coordinates and can be applied to an adiabatic description of the entire fission process.
