dc.description.abstract | By expanding the Bargmann-Segal integral transform of nomi and overlap kernels in appropriately SU(3) coupled Bargmann space functions, the calculation of norm and overlap matrix elements in a cluster model basis is reduced to purely algebraic techniques involving the algebra of SU(3) recoupling transformations. This technique has been further developed to make calculations possible for systems of two heavy fragments other than closed-shell nuclei. In one application of the method, analytic expressions are given for the norms of binary fragment systems in which a light fragment of mass number [function of (italic small f)], [function of (italic small f)] [les] 4, is combined with a heavy fragment of mass number A-[function of (italic small f)], with A-[function of (italic small f)] [les] 24. The A-[function of (italic small f)] fragment nuclei with different p- and sd-shell structure illustrate somewhat different problems in the recoupling technique. In a second application, spectroscopic amplitudes are calculated for the most important open channels of the 12C+ 12C resonances. Eigenvalues and eigenvectors of the antisymmetrizer are evaluated in a "molecular basis" of the 12C + 12C system, in which each 12C nucleus is assumed to have SU(3) symmetry (04) with internal rotational excitations of 0+,2+ and 4+. Reduced width amplitudes are calculated connecting such normalized, fully antisymmetrized molecular basis states to exit channels which include: [alpha]+20Ne with 20Ne internal functions of (80) SU(3) symmetry, (K = 0+ band, and (82) SU(3) symmetry, (K = 2- band); 16O+8Be; and 23Na+p or 23Mg+n fragments with 23Na or 23Mg excitations in rotational bands of SU(3) symmetry (83). | en_US |
