Under the Gaussian Overlap Approximation (GOA), the TDGCM leads to a local, time-dependent Schrödinger equation in a multi-dimensional collective space. Using the TDGCM, we have calculated the fragment mass distri butions, be-fore prompt neutron emission, for the 235 U( n;f ) and 239 Pu( n;f ) reactions, and for incident neutron energies E n ranging from thermal to 5 MeV. In the TDGCM, one assumes that a many-body wave function is given as a superposition of many Slater determinants, (t) = X a f a(t) a(t); (1) where f a is a weight function and a is a Slater de-terminant with single-particle wave functions f˚ aig. Containers. 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. It was established on 17 July 1979 by. This is the TDGCM+GOA equation. Unit 803, 8F Reach Building, Diosdado Macapagal Blvd. 2 TDGCM+GOA approach to compute fission yields The time-dependent generator coordinate method (TDGCM) provides a fully quantum mechanical description of the time evolution of the fissioning system. 0. Our Blogs. 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. ph. regnier@cea. It was. The dynamics of low-energy induced fission is explored using a consistent microscopic framework that combines the time-dependent generator coordinate method (TDGCM) and time-dependent. Finally, we highlight several exploratory studies related to a TDGCM built on time-dependent generator states. Physics. 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]. , Bry. The TDGCM+GOA approach to compute fission yields The time-dependent generator coordinate method (TDGCM) provides a fully quantum mechanical descrip-tion of the time evolution of the fissioning system. coordinate method (TDGCM) [19] to compute the induced fission fragment charge and mass distributions [20–24]. First, a series of constrained EDF calculations map the configuration and potential-energy landscape of the fissioning system for a small set of collective variables (in this work, the axial quadrupole and octupole moments of the nucleus).
