Abstract
Three interference asymmetry effects in the angular distributions of fragme nts originating from U-233 fission induced by resonance neutrons were measu red. The energy dependences of the asymmetry factors being studied show siz able irregularities that are associated, according to modern theory, with t he interference of s and p resonances at the stage of a compound nucleus. T he basic features of weak p-wave resonances in the low-energy region were o btained from a global theoretical analysis of the asymmetry factors as func tions of energy. The first estimates of nuclear matrix elements of weak int eraction were derived for a few p-wave resonances. (C) 2000 MAIK "Nauka/Int erperiodica".
