Realistic single-particle K-matrix for deformed and fissioning nuclei

Journal Article · · Nuclear Physics. A
; ;
A low-order approximation to the Brueckner-- Goldman densitydependent single-particle reaction matrix is used. The effective single-particle Hamiltonian is nonlocal and depends on a smeared density. The isospin depcndence, spin- orbit, center-of-mass, and Coulomb corrections are performed in a realistic manner. A large orthogonal (spherical/deformed) oscillator basis or a nonorthogonal basis consisting of two overlapping harmonic oscillators is used to diagonalize the Hamiltonian in an iterative self-consistent scheme. The nonlocality, the density-dependent terms, and the Coulomb terms are expanded in Gaussian forms by using a linearized high-speed technique. Results for the total BE, s.p. energies. quadrupole moments, radii, and proton and neutron density distributions of light nuclei are found to be in good agreement with experiment. Fission effects in the reactions /sup 8/Be yields alpha + alpha and /sup 32/ S yields /sup 16/0 + /sup 16/O are studied. (auth)
