Fission via compound states andJ^πKA. Bohr's channels: what we can learn from recent studies with slow neutrons

Abstract

Abstract. Last data on angular correlations of fission fragments from slow (s-wave) neutron induced binary fission of spin-aligned nuclei 235 U are discussed in the context of J π K A. Bohrs channels. Special attention is paid to K = 0 channel. Reasons for its suppression are specified for compound nucleus states of negative parity. A brief overview of recent data on T-odd angular correlations in ternary and binary (with emission of a third particle, a neutron or γ-quantum) fission induced by slow polarized neutrons is presented. On the basis of the developed theoretical approach it is shown that a valuable information on J π K fission channels at scission point can be inferred from these T-odd angular correlations.
