Restricted Hartree-Fock Calculations in Light Nuclei / Hartree-Fock Calculations

Manning, Martin 10 1900 (has links)
This thesis is missing pages 152 and 194, neither of which are in the other copies of this thesis. -Digitization Centre / Restricted Hartree-Fock calculations for light even-even nuclei have been carried out using simple effective interactions. The primary emphasis is on the nature of the intrinsic states, and, in particular, on the deformation of these states. In order to find the equilibrium deformations a representation of deformed cylindrically symmetric states is used. A self-consistent technique for finding the equilibrium size and shape is proposed. There is a strong secondary emphasis on the role of the effective interaction, and four rather different interactions are used. Two of these incorporate a dependence on the density on the nuclear system, and this density dependence improves the systematic behaviour of the energies and sizes of light nuclei. / Thesis / Doctor of Philosophy (PhD)

No. of bitstreams: 1 tese_3720_.pdf: 891755 bytes, checksum: cfb138ba0e859da4be21894caaa8da28 (MD5) Previous issue date: 2009-10-13 / Recentemente, conjuntos de bases de contração segmentada de qualidade dupla, tripla e quádrupla zeta de valência mais funções de polarização (XZP, X=D, T e Q, respectivamente) para os átomos do H até Ar foram apresentados. Neste trabalho, com o objetivo de termos uma melhor descrição das polarizabilidades, o conjunto QZP foi aumentado com funções difusas (de simetrias s e p) e funções de polarização (de simetria p, d, f e g), que foram escolhidas para maximizar a polarizabilidade média de dipolo aos níveis UHF e UMP2, respectivamente. Aos níveis de teoria HF e B3LYP, foram calculados momentos de dipolo elétrico e polarizabilidades estáticas para uma amostra de moléculas. Foram feitas comparações com dados experimentais e com resultados obtidos com um conjunto de base similar, cujas funções difusas foram otimizadas para um ânion de energia no estado fundamental.
