【 摘 要 】

Neutron-induced reaction cross sections are important for applications such as neutron transport and heating and radio-chemical diagnostics. Data on these reactions usually exist for neutron energies below 14 MeV. In a neutron-induced reaction the residual nucleus is typically left in a highly excited state which subsequently decays via y-cascades to the ground state. High-resolution measurement of the prompt y-rays in such a reaction allows identification of specific residual nuclei by the characteristic energies of transitions between the low-lying levels.
