Nuclear magnetic dipole properties and the triaxial deformation
Nuclear magnetic dipole properties of ground bands and γ-vibrational bands are studied for the first time using the triaxial projected shell model approach. The study is carried out for the Dy and Er isotopic chains, ranging from transitional to well-deformed region. It is found that the g-factor ratio of the 2 state in ground bands to that of γ-bands, r = g(2, γ-vib)/g(2, ground), varies along...
متن کاملTriaxial Galaxies with Cusps
We have constructed fully self-consistent models of triaxial galaxies with central density cusps. The triaxial generalizations of Dehnen's (1993) spherical mass models are presented, which have densities that vary as r −γ near the center and r −4 at large radii. We computed libraries of ∼ 7000 orbits in each of two triaxial models with γ = 1 (" weak cusp ") and γ = 2 (" strong cusp "); these tw...
متن کاملTriaxial Black-hole Nuclei
We demonstrate that the nuclei of galaxies containing supermassive black holes can be triaxial in shape. Schwarzschild’s method was first used to construct self-consistent orbital superpositions representing nuclei with axis ratios of 1 : 0.79 : 0.5 and containing a central point mass representing a black hole. Two different density laws were considered, ρ ∝ r−γ , γ = {1, 2}. Only non-chaotic o...
متن کاملv 1 8 N ov 1 99 9 Systematic Study of Triaxial Deformation in the Relativistic Mean Field Theory
We use the relativistic mean field (RMF) theory to systematically study the change of deformation of even-even nuclei in the proton-rich Xe region. We investigate the appearance of triaxial deformation in 25 nuclei in the region covering Z = 50 − 58 and N = 64 − 72 by performing constrained, triaxially symmetric RMF calculations of their energy surfaces. We include pairing correlations using th...
متن کاملStrength and Deformation Characteristics of Granular Materials under Extremely Low to High Confining Pressures in Triaxial Compression
— The shearing strength and volumetric relationship of granular materials change notably with a variation of confining pressure. In this study the effect confining pressure on the mechanical behavior of granular materials were observed using discrete element method (DEM). The triaxial tests were conducted on seven specimens covering a range from extremely low to high confining pressures. Each i...
