Cross-Sections for the ⁸⁹Y(n,n') ^89mY and ⁸⁹Y(n,2n)⁸⁸Y Reactions

摘要

Excitation curves for the ⁸⁹Y(n,n')^89mY reaction were measured in the neutron energy range 3–18 MeV and for the ⁸⁹Y(n,2n)⁸⁸Y reaction in the energy range 13–18 MeV. The results obtained were interpreted in terms of the statistical nuclear reaction model. The problem of the competition between electromagnetic radiation emission acd neutron emission from the highly excited compound nucleus states is discussed.
