FISSION FRAGMENT ANGULAR ANISOTROPIES AND INERTIA PARAMETERS
An analysis of selected fission fragment angular distributions from helium-ion induced fission is made using an exact theoretical expression. Theoretical anisotropies obtained with the transition state model are compared with their corresponding values deduced from the statistical scission model. The nuclear moment of inertia extracted from the model calculations are compared with their est...
متن کاملHow Fission Yeast Fission in the Middle
In fission yeast, we propose that the division plane may be positioned by the position of the premitotic nucleus, perhaps by a signal emanating from the nucleus. Gene products involved in the assembly of the ring and its temporal and spatial controls are beginning to be characterized. Some of these, such as mid1p, may be involved in signals that position the division site. In animal cells, the ...
متن کاملMultimodal Fission
An important issue for communication processes in general, and for multimodal interaction in particular, is the information output arrangement and organization (multimodal fission). Considering information structure, intonation, and emphasis for the output by speech, considering moreover spatio-temporal coordination of pieces of information for visual (video, graphics, images, and texts) output...
متن کاملOverview of Fission Safety for Laser ICF Fission Energy
This paper reviews fission safety design principles and approaches for coupling inertial confinement fusion (ICF) to a subcritical fission blanket, in Laser ICF Fission Energy (LIFE) power plants. LIFE power plants use fuel derived from either spent fuel from fission reactors, or from natural uranium or thorium. By using fusion neutrons, LIFE plants can fission a large fraction of the heavy met...
متن کاملFission dynamics within time-dependent Hartree-Fock: Boost-induced fission
Methods: Following upon the work presented in Ref. [1], quadrupole-constrained Hartree-Fock calculations are used to create a potential energy surface. An isomeric state and a state beyond the second barrier peak are excited by means of instantaneous as well as temporally extended gauge boosts with quadrupole shapes. The subsequent deexcitation is studied in a time-dependent Hartree-Fock simula...
