Abstract

Measurements of the spectrum of

γ

rays from the reaction

{}^{208}{Pb} (n, γ) {}^{209}{Pb}

have been made at incident neutron energies of 9.2, 11.2, and 13.2 MeV. The observed spectral shapes disagree strongly with the predictions of compound-nuclear theory and agree quite well with those predicted by semidirect (collective) capture theory.
