1550-7998=20 We discuss spatial fluctuations in the gravitational wave background arising from unresolved Galactic binary sources, such as close white dwarf binaries, due to the fact the galactic binary source distribution is anisotropic. We introduce a correlation analysis of the two data streams of the Laser Interferometer Space Antenna (LISA) to extract spherical harmonic coefficients of the...

GCM study of hexadecapole correlations in superdeformed 194 Hg. Abstract The role of hexadecapole correlations in the lowest superdeformed band of 194 Hg is studied by self consistent mean field methods. The generator coordinate method with particle number projection has been applied using Hartree-Fock wave functions defined along three different hexadecapole paths. In all cases, the ground sta...

using hartree-fock su-sheriffer-heeger (hf-ssh) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 nf) on the intensity of an external in plane static electric field at zero temperature. we identify a transition from the magnetic triplet stat...

We investigate the effects of nuclear quadrupole and hexadecapole couplings on the average angular momentum in sub-barrier fusion reactions. This quantity could provide a probe for nuclear shapes, distinguishing between prolate vs. oblate quadrupole and positive vs. negative hexadecapole couplings. We describe the data in the O + Sm system and discuss heavier systems where shape effects become ...

We have investigated collisions between transversely polarized electrons and Ar, in which the Ar is simultaneously ionized and excited to the Ar+*f3p4sDd4pg states. The Stokes parameters of the fluorescence emitted in the following transitions was measured: sDd4s D5/2− s Dd4p F7/2 s461.0 nmd, s Dd4s D5/2 − sDd4p F5/2 s463.7 nmd, s Pd3d D5/2− s Dd4p D5/2 s448.2 nmd, and s Dd4s D3/2− s Dd4p P3/2 ...

The effect of an axially symmetric hexadecapole term is investigated in a strongly deformed quadrupole potential. While the system is nonintegrable and shows significant chaotic behaviour classically, the quantum mechanical treatment not only produces a general smoothing effect with regard to chaos but even yields a pronounced shell structure at certain hexadecapole strength parameter values fo...

Electric moments are relevant for many phenomena caused by intermolecular interactions [1-4]. Recent work [5-13] has provided evidence that models relying on the knowledge of the electric moments of the monomers can be used to predict molecular structures and properties of weakly bonded van der Waals systems. Not all electric moments are easily amenable to experiment [2]. Experimental determina...

A role of the multipole interaction in the description of the △I=4 staggering phenomenon is investigated in a model consisting of a single-j shell filled by identical nucleons. Exact diagonalization of the quadrupole-plushexadecapole Hamiltonian shows that the hexadecapole-hexadecapole interaction can produce a △I=4 periodicity in the yrast sequence.
