General Formulation Of The Scattered Matter Waves By A Quantum Shutter, Yusuf Zi̇ya Umul

Turkish Journal of Physics

The scattering process of matter waves by a quantum shutter is investigated by using the spectrum integral representation. The scattered fields are expressed in terms of the Fresnel function. It is shown that the obtained equation gives the Moshinsky function for a one dimensional problem of the plane wave. Also a general integral representation is derived for two dimensional problems. The scattering of matter waves for some special wave-packets are examined analytically and numerically.

Electric Multipole Moments Of Some Diatomic Molecules Molecules, M. Özgür Sezer, Ayhan Özmen, Hüseyi̇n Yüksel

Turkish Journal of Physics

Molecular Electric Multipole Moment (MEMM) integrals have been derived for diatomic molecular systems, and then some lower multipole moments as dipole moments and quadrupole moments have been calculated for some diatomic molecules. The calculations have been performed by using our analytical formula over Slater-Type orbitals (STOs) with Cade and Huo's basis sets and the GAMESS program package working with Gaussian-Type basis sets (GTOs). The expressions which involve factorials are given in terms of binomial coefficients in order to speed up calculations. The results have been obtained in agreement with data found in the literature.

Kantowski-Sachs Viscous Fluid Cosmological Model With A Varying \Lambda, Sharad Kandalkar, Pramod Khade, Sunita Gawande

Turkish Journal of Physics

We study the Kantowski-Sachs cosmological model filled with viscous fluid in the presence of cosmological term \Lambda. To get a deterministic solution, a condition between metric potentials is used. The viscous coefficient of bulk viscous fluid is assumed to be a power function of mass density, whereas coefficient of shear viscosity is considered proportional to scale of expansion in the model. It is found that the cosmological constant \Lambda is positive and is a decreasing function of time, which is supported by results from recent supernova observations. Some physical and geometrical properties of the models are also discussed.

The numerical analysis of energy dependence of the spin asymmetry, the angular electron-neutrino (e\nu) correlation and the charge asymmetry coefficients shows that the relative contribution of the second-class current (SCC) tensor form factor can reach some tens of percents in the case of particular values of final nuclei alignment and polarization.


Behavior Of Transition Amplitude And Evolution Of The Energy Of Quantum Kicked Rotator, Abdolrasoul Gharaati Jan 2009

Behavior Of Transition Amplitude And Evolution Of The Energy Of Quantum Kicked Rotator, Abdolrasoul Gharaati

Turkish Journal of Physics

I give certain analytical properties of quantum kicked rotators, both theoretic and observed from computation. I give an expression for the wave function between two successive impulses. An element of the transition matrix, the matrix that takes the wave function from one impulse to another, exponentially falls away from the main diagonal. The decay parameter is given for a few special cases of a periodic potential. Finally, the transition matrix is used to derive the time evolution of the energy for periodic cases and for fundamental resonances. The empirical expressions of Dorizzi et al. are compatible with our analytical results.

The effective variance of this fission process is also calculated. The present numerically …


Effect Of A Wiggler Magnetic Field And The Ponderomotive Force On The Second Harmonic Generation In Laser-Plasma Interactions, Hassan Ranjbar Askari, Maryam Noroozi Jan 2009

Effect Of A Wiggler Magnetic Field And The Ponderomotive Force On The Second Harmonic Generation In Laser-Plasma Interactions, Hassan Ranjbar Askari, Maryam Noroozi

Turkish Journal of Physics

In this paper, we consider second harmonic generation and its phase-matching in an underdense plasma in the presence of a wiggler magnetic field. Wiggler magnetic field plays both a dynamic role in producing the traverse harmonic current and a kinematical role in ensuring phase-matching. The inertial ponderomotive force \rho (\vec{u} . \vec \nabla) \vec{u} is a source of harmonic generation. \vec{u} beats with itself to produce a different harmonic. The inertial ponderomotive force can also affect the efficiency of second harmonic generation; and its effect on second harmonic generation is also considered.

Signature Splitting And Signature Inversion Of Rotational Bands In Odd-Odd Nuclei In Rare-Earth Region, Manal Mahmoud Sirag

Turkish Journal of Physics

Anomalous signature splitting and signature inversion for the configuration \pi h_{11/2} \otimes \nu i_{13/2} in rotational bands of odd-odd nuclei have been studied using the energy staggering index S(I) as a function of spin I. The unfavored signature index was found lying lower than the favored one. A systematic look at the features of this signature inversion in a series of nine lighter rare earth nuclei in the region around A \sim 160 (Z~=~65-75, N~=~89-101) are presented. The analysis reveals an anomalous signature splitting for this configuration. The magnitude of signature splitting at low spins decreases as the proton number …

Tau Sleptons And Tau Sneutrino Decays In Mssm Under The Cosmological Bounds, Levent Selbuz, Z. Zekeri̇ya Aydin

Turkish Journal of Physics

We present a numerical investigation of the fermionic two-body decays of tau sleptons \tilde \tau_{1,2} and \tau sneutrino in the Minimal Supersymmetric Standard Model with complex parameters. In the analysis we particularly take into account the cosmological bounds imposed by WMAP data. We plot the CP-phase dependences for each fermionic two-body channel of \tilde \tau_{1,2} and \tau sneutrino and speculate about the branching ratios and total (two-body) decay widths. We find that the phase dependences of the decay widths of the third family sleptons are quite significant which can provide viable probes of additional CP sources. We also draw attention …

Turkish Journal of Earth Sciences

The Karaçayır syenite, intruding the Palaeozoic crustal metamorphics and unconformably overlain by Upper Paleocene to Eocene Tokuş formation in the north of Sivas (east-central Anatolia), has been studied with respect to ^{207}Pb-^{206}Pb single zircon evaporation, biotite ^{40}Ar-^{39}Ar, and apatite fission-track geothermochronology. ^{207}Pb-^{206}Pb single zircon evaporation dating yields an age of 99.0±11.0 Ma (Cenomanian-Turonian) which is considered to be the intrusion age. Biotite ^{40}Ar-^{39}Ar age determination gives a cooling age of ca. 65 Ma. Apatite fission-track dating, combined with T-t modeling based on track-length distribution data, determines a fast tectonic exhumation with an uplift rate of > 1 mm/a which occurred 58-61 …
