The purpose of the present study is to show that the TDGCM+GOA based on nuclear energy density functionals can equally well beIn addition, the tdgcm predicts two distinct asymmetric modes for the ssion of 254Fm. Finally, the dynamical TDGCM calculation reproduces the asymmetric yield distribution of the low-energy fission of Hg180, especially for the peak positions.
