in this paper, lagrangian and equations describing one-dimensional anisotropic non-heisenberg model are studied. in this study we used the generalized coherent states in real parametrizations and the feynman path integral for these states in su(3) group. these equations describe nonlinear dynamics of non-heisenberg ferromagnetic chain completely. solutions of these equations are magnetic solito...

We describe our high-resolution measurements of the 133Cs 6p (2)P(3/2) state hyperfine structure. An optically narrowed diode laser excites perpendicularly a highly collimated atomic beam. The spectra are calibrated with a stable reference diode laser using a rf locking scheme allowing us to determine the splittings with an accuracy of < or =2 kHz, an order of magnitude better than previous res...

The Sun’s orbital motion around the Solar System barycentre contributes a small quadrupole moment to the gravitational energy of Mercury. The effect of this moment has until now gone unnoticed, but it actually generates some precession of Mercury’s orbit. Therefore the residual 43arcsec/cy, currently allocated to general relativity, has to account for this new component as well as a reduced rel...

The interacting boson model is extended to describe the spectroscopy of superdeformed bands. Microscopic structure of the model in the second minimum is discussed and superdeformed bosons are introduced as the new building blocks. Solutions of a quadrupole Hamiltonian are implemented through the 1=N expansion method. E ects of the quadrupole parameters on dynamic moment of inertia and electric ...

The magnetic fields of white dwarfs distort their shape generating an anisotropic moment of inertia. A magnetized white dwarf which rotates obliquely relative to the symmetry axis has a mass quadrupole moment which varies in time, so it will emit gravitational radiation. LISA may be able to detect the gravitational waves from two nearby, quickly rotating white dwarfs.

Intermolecular interactions involving aromatic pi-electron density are widely believed to be governed by the aromatic molecular quadrupole moment, Theta(zz). Arene-cation binding is believed to occur primarily with negative Theta(zz) aromatics, and arene-anion binding is believed to occur largely with positive Theta(zz) aromatics. We have performed quantum mechanical computations that show the ...

The electric-quadrupole coupling constant of the ground states of the proton drip line nucleus 20Na(Iπ = 2+, T1/2 = 447.9 ms) and the neutron-deficient nucleus 21Na(Iπ = 3/2+, T1/2 = 22.49 s) in a hexagonal ZnO single crystal were precisely measured to be |eqQ/h| = 690 ± 12 kHz and 939 ± 14 kHz, respectively, using the multi-frequency β-ray detecting nuclear magnetic resonance technique under p...
