Coulomb Effect on the Proton-Proton Low Energy Scattering Parameters and Separable PotentialsVo-Dai, Thien 09 1900 (has links)
<p> We study the Coulomb effect on the proton-proton low-energy scattering parameters when all other effects are represented by a separable potential.</p> <p> For this purpose, we present a formulation for the scattering of two particles via a separable potential. We treat the same problem when any potential, particularly a Coulomb potential or a separable potential, is added to the separable potential. The properties of scattering from a separable potential plus a (local or non-local) potential lead us to the possibility of obtaining a one term separable potential equivalent to a two term separable potential, and a model for the nuclear potential as a sum of a separable potential and a non-separable potential.</p> <p> We determine, to the first order in Me^2/β where β^-1 is the range of the separable potential, the parameters for Yamaguchi's and Naqvi's separable potentials from proton-proton scattering data. We use these parameters to calculate the low-energy proton-proton scattering parameters when the Coulomb interaction is removed. Our results show that the shape dependence of these parameters are somewhat larger than obtained by Heller et al in their investigation on local potentials. Implications of our results concerning the charge symmetry and charge independence of the nuclear forces are discussed.</p> / Thesis / Master of Science (MSc)

Topics on the Nucleon-Nucleon InteractionGoodfellow, John F. 09 1900 (has links)
<p> Some aspects of the nucleon-nucleon interaction are
investigated. Phase-equivalent families of rank-two separable
potentials are derived by inverting the on- shell phaseshifts.
The off-shell properties of these potentials are
examined and shown to be well behaved. These and additiona l
pairs of phase-equivalent local and separable potentials
are included in a proton-proton bremsstrahlung calculation.
In particular, the off-shell dependence of the cross sections
is shown to be small. </p> / Thesis / Doctor of Philosophy (PhD)
