Description
Summary:Within the framework of the generalized peripheral model (GPM), the process of proton stripping in the [sup.12]C[([sup.3]He, d).sup.13]N reaction to the first excited resonance state (E* = 2.365 MeV and [J.sup.[pi]] = [1/2.sup.+]) of the [sup.13]N nucleus at energies E[sup.3]He = 16, 17, 18, 34, and 81.4 MeV is considered. Its proton width [[GAMMA].sub.p] has been determined. It is shown that taking into account three-body Coulomb effects in the proton transfer reaction significantly changes the absolute value of the calculated differential cross section, which leads to a decrease in the extracted [[GAMMA].sub.p] value. The obtained value of proton width [[GAMMA].sub.p] = 30.1 [+ or -] 0.8 keV for the [sup.13]N nucleus (E* = 2.365 MeV) is in good agreement with the experimental value of 31.7 [+ or -] 0.8 keV. Keywords: nuclear physics, charged particle stripping reaction, resonant state, particle transfer mechanism, peripheral model, differential cross section, three-body Coulomb dynamics, resonance width, nuclear vertex constant, asymptotic normalization coefficient.
