Deuteron Universal Phenomenological Optical Potential, As Well As Protons And ~ (58) Ni Reaction Theoretical Calculations

This thesis contain two contents, one is the research of deuteron global opticalmodel potential, the other is the nuclear data calculation.The deuteron global optical potential as a function of radius and the volumeintegrals of the optical potential are calculated and analyzed. We could see that the depthof the real central of potential decreases with increasing the radius of, and decreases withincreasing the energy of the incident dueteron. The depth of the imaginary part potentialof surface absorption decreases with increasing the energy of the incident dueteron, butthe depth of the imaginary part potential of volume absorption increases with increasingthe energy of the incident dueteron. In the same energy of the incident dueteron, the depthof the imaginary part potential of volume absorption increases with increasing massnumber. The volume integrals of the potential decreases with increasing mass number.The volume integrals of the real central potential decreases with increasing the energy ofthe incident deuteron, and the volume integrals of the imaginary part potential increaseswith increasing the energy of the incident deuteron. The results show that the deuteronglobal optical model potential are reasonale in physically.The inelastic scattering angular distributions of deuteron induced reaction arecalculated and analyzed by using the optical model and the distorted Wave Bornapproximation theory. Theoretical calculations are compared with existing experimentaldata and the calculated results are in good agreement with the experimental data, and thedeformation parameters for excites levels are obtained.The other is calculation and analysis of p+⁵⁸Ni reactions at incident energies fromthreshold to 250 MeV. According to experimental data of nonelastic cross sections andelastic scattering angular distributions for p+⁵⁸Ni reactions, nonelastic cross section forp+^natNi and p+⁶³Cu reactions, and elastic scattering angular distributions for p+⁶⁸Znreactions, an optimal set of proton optical potential parameters for ⁵⁸Ni was obtained at incident proton energies below 250 MeV. All cross sections, elastic and inelasticscattering angular distributions of proton induced reaction, energy spectra, and especiallydouble differential cross sections for neutrons, protons, deuterons, tritons, heliumparticles and alpha particles emission are calculated and analyzed for p+⁵⁸Ni reactions,using the optical model, the distorted Wave Born approximation theory, Hauser-Feshbachtheory with width fluctuation correction and evaporation model, the pre-equilibriumstatistical theory based on exciton model and the intra-nuclear cascade model. In thepre-equilibrium statistical theory, the improved pick-up mechanism for compositeparticles emissions and Pauli principle in the calculation of exciton state densities areaccommodated. Theoretical calculations are compared with existing experimental data, inmost cases, the calculated results are in good agreement with the experimental data.These data are very significance for either research of nuclear reaction theory orapplication of nuclear engineering.
