ABSORPTION CROSS-SECTION OF CHARGED PARTICLES BY NUCLEI IN THE GROUND AND EXCITED STATEFEI, Obninsk, USSR O.T. Grudzevich, A.V. Zelenetsky, V.I. Plyaskin IATE, Obninsk, USSR In the frameworks of modern theoretical models of nuclear reactions an analisis of the excitation functions and emission spectra of the neutron threshold reactions at neutron energies up to 20 MeV has been done. The results of the analisis indicate the considerable difference between the alpha-particle transmission coefficients for the excited and ground state nucleus. KEYWORDS: Nuclear reaction, absorption cross-section, charged particle emission spectra, excited nucleus, ground state |
