Fourier-over-spheroid shape parametrization applied to nuclear fission dynamics
Fourier-over-spheroid shape parametrization applied to nuclear fission dynamics
We propose a new, rapidly convergent shape parametrization, the so-called Fourier-over-spheroid (FoS) approach, to model fission of heavy nuclei. Four collective coordinates are used to characterize the shape of the fissioning system: its elongation, left-right asymmetry, neck size, and nonaxiality. The potential energy landscape is computed within the macroscopic-microscopic approach, …
