SOME SUGGESTIONS ABOUT THE RESEARCH OF THE E2(T = 1) RESONANCE EXCITATION BY (N, GAMMA) REACTION ON CERIUM

Determining at microscopic level the interaction responsible for the excitation of collective states of Ce-140 makes it possible to use in a coherent way the direct-semidirect model in the study of the Ce-14O(n half arrow pointing right, gamma) reaction. Computations of differential cross-sections give useful pieces of information about the effects caused by the excitation of the isovector quadrupole giant resonance on the gamma-ray emission geometry, closely connected with the polarization state of the incident neutron. Thus, the results supply helpful suggestions on a possible experimental research of the E2(T = 1) excitation by means of the radiative capture reaction.
