Angular distributions of deuterons elastically and inelastically scattered on 7 Li nuclei with excitation of the 0.478 MeV (J π = 1/2 − ) level, and tritons from the 7 Li(d, t) 6 Li reaction, corresponding to transitions to the ground (J π = 1 + ) and low-lying excited states (J π = 3 + and 0 + ) of the 6 Li nucleus were measured at the 25 MeV energy. The experimental data were analyzed within the framework of the coupled reaction channels and a modified distorted-wave methods. The values of the spectroscopic factors and the asymptotic normalization coefficients for the 7 Li → 6 Li + n vertex were extracted.
In this paper, we present new experimental data measured at E p = 29.9 MeV for the inclusive reactions (p, xp) and (p, xα) on nucleus 56 Fe. We investigate the adequacy of the theoretical models in explaining the measured experimental data, and we determine the contributions of multistep direct and multistep compound processes in the formation of the cross-sections. We show that the traditional frameworks are valid for the description of the new experimental data, and our measurements agree with previous measurements for the (p, xp) and (p, xα) reactions on the 54 Fe nucleus. The only exception is within the energy region of E p = 15 and 25 MeV for both reactions, where the cross-section for the 56 Fe nucleus is smaller than the cross-section for the 54 Fe nucleus.
New experimental data for the inclusive reactions (p,xp) and (p,xd) on isotopes of the nuclei 90,92 Zr and 92 Mo, have been measured at E p ϭ30.3 MeV, which has not been investigated in detail so far. We show the extension of the preequilibrium reactions to this energy region and interpret the results of these experiments. Moreover, we display the mechanism of the reaction and the level of energy dependence. The adequacy of the theoretical models in explaining the measured experimental data is also discussed. In our theoretical analysis, the contributions of multistep direct and compound processes in the formation of cross sections are determined and we assert that the traditional frameworks are valid for the description of the experimental data.
