Abstract (english)

Collective mass tensors derived in the cranking approximation to the adiabatic time-dependent Hartree-FockBogoliubov (ATDHFB) method are employed in a study of induced fission dynamics. Together with a collective
potential determined in deformation-constrained self-consistent mean-field calculations based on nuclear energy
density functionals, the mass tensors specify the collective Hamiltonian that governs the time evolution of the
nuclear wave function from an initial state at equilibrium deformation, up to scission and the formation of
fission fragments. In an illustrative calculation of low-energy induced fission of 228Th, 230Th, 234U, and 240Pu, we
compare the nonperturbative and perturbative cranking ATDHFB mass tensors in the plane of axially symmetric
quadrupole and octupole deformations, as well as the resulting charge yields.
