Microscopic description of the torque acting on fission fragments

When two fragments are created in a fission decay, any torque due to nuclear and Coulomb interaction can change the fragment's angular momentum. This paper explores character magnitude of momentum as function initial conditions around scission point using time-dependent Hartree-Fock theory. To understand acting on fragments, Frozen method is also used determine collective potential at scission. Two $^{240}\mathrm{Pu}$ channels $(^{132}\mathrm{Sn}+^{108}\mathrm{Ru}$ $^{144}\mathrm{Ba}+^{96}\mathrm{Sr})$ studied. These cover different shapes (spherical, quadrupole, octupole deformation) fragments. It found that generated by after mainly collective, while this not case for The competition between rotational modes (bending, wriggling, twisting) discussed shows perpendicular axis.
