Angular momentum of fission fragments from microscopic theory

Bases for spin systems and qudits from angular momentum theory

Spin bases of relevance for quantum systems with cyclic symmetry as well as for quantum information and quantum computation are constructed from the theory of angular momentum. This approach is connected to the use of generalized Pauli matrices (in dimension d) arising from a polar decomposition of the group SU2. Numerous examples are given for d = 2, 3 and 4.

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...

Angular Distribution of Fragments from Fission Induced by Heavy Ions in Gold and Bismuth

We present the results of measurements of the angular distribution lg7 and Bi of fission fragments produced by irradiation of Au 209 with 11 various heavy ions. The projectiles, B , G'l2, N14, and 016, had energies from a few MeV above the Coulomb barrier to 10.4 MeV per nucleon. The gross features of these results can be explained by use of a model and parameters that have been used by others ...

Long - Range Fission Fragments from Radiogemc Lead ?

Fission tracks with a range 19% longer than tracks produced by uranium fission fragments were observed on mylar foils after a three year underground (100 m w. e.) exposure to 3600 cm2 of radlogemc lead. Ordinary lead which was simultaneously exposed to mylar foils under the same conditions yielded a background effect of only 3% of the effect from radiogenic lead. The observed long-range tracks ...
