ON THE ANGULAR-DISTRIBUTIONS OF FRAGMENTS IN THE FISSION OF ORIENTED U-235 NUCLEI INDUCED BY RESONANCE NEUTRONS

Angular distributions of fragments in the fission of oriented nuclei induced by resonance neutrons reveal peculiarities that differ sharply from the characteristics of angular distributions of fission fragments for the same compound nucleus in reactions with spinless targets. Above all, this manifests itself in suppressing the states with K = 0. The influence of a cutoff of statistical distributions of fission widths of resonances from below on these angular distributions because of limited in experimental sampling or a slightly fluctuating component in the fission width is investigated. This cutoff is shown to deform the angular distributions in a way that is desired, at least qualitatively.
