Inelastic Scattering of Protons fromO16and the Spin-Dependent Part of the Effective Interaction

Cross sections for production of the 15.10-MeV and other astrophysically significant gamma-ray lines through excitation and spallation ofC12andLang1, Werntz2, Crannell3 et al. 1987Phys. Rev. C

“…To arrive at a total cross section, Eq. 28is integrated analytically to obtain (29) All of the angular dependence of the differential cross section is contained in three terms in Eq. (27).…”

“…For confirmation, the gamma-ray production cross sections for the reaction 160(p,P'-Y6.129)160 have been estimated from the excitation cross sections. Austin et al 29 present measurements of the total excitation cross sections for the reactions 160(p,p')160*(6.130 and 8.872) for 39.7-MeV protons. When these are combined with an estimate of the 11.080-Me V excitation cross section and the known branching ratios for decay through the 6.130-MeV state, the 6.129-MeV gamma-ray production cross section is estimated to be 34.8 ± 2.0 mb for 40-MeV protons.…”

“…This allowed the angular dependence of the cross section to be determined while including only uncertainties in the counting statistics. When the Legendre polynomial coefficients, b l , are computed this way, the total cross section is given by in analogy to Eq (29)…”

Fluctuations in inelastic proton scattering from58Ni in the energy range 17.1 to 20.6 MeV

“…Recently, there has been a number of microscopic analyses [1][2][3][4][5] of inelastic proton scattering [5,6,7] to unnatural parity final states. Interest in these transitions comes from the expectation [1,5] that some unnatural parity states might be described by quite simple shell model wave functions.…”
