Continuum Spectra Analysis of (p, d) and (n, d) Reactions on Bi in Several tens of MeV Energy Region

摘要

Theoretical analyses of the double differential cross sections for proton and neutron induced deuteron pickup reactions on ~(209)Bi are described. Neutron induced reaction cross-section data were analyzed at incident energies from about 41 MeV to 65 MeV and at 20° laboratory angle, while proton induced reaction cross-section data were analyzed at the incident energy of 42 MeV and at 25° laboratory angle. Spectrum regions are treated in the direct reaction scheme, i.e., several tens of MeV energy region. The double differential cross section - energy spectra were analyzed using the DWBA-based cross sections and the asymmetric Lorentzian form strength response function having energy dependent spreading width. Both the (n,d) and (p,d) spectra are fairly well reproduced by the theoretical calculations in the tens of MeV energy region.
