THE POWER SPECTRUM ASSOCIATED WITH A KINK CHAIN OSCILLATING IN A NON-STOKESIAN ATMOSPHERE OF PARAELASTIC INTERSTITIALS OGURTANI, T; GUNGOR, R (Elsevier BV, 1994-09-01) The power spectrum of a built-in kink chain oscillating in an atmosphere of paraelastic interstitials was investigated numerically using a fast Fourier transform technique. Above a sharply defined value of the strain amplitude, odd-harmonic generation is observed only at the low-temperature side of the dislocation relaxation peak associated with interstitial-kink interaction. At moderately high strain amplitudes, a strong enhancement of the harmonics situated in the immediate vicinity of the natural resonan...
The influence of a longitudinal magnetic fields on a non-uniform positive column Akbar, D.; Bilikmen, S. (Wiley, 2007-01-01) The variations of plasma parameters of a dc discharge in a non-uniform magnetized plasma were measured using fast floating double Langmuir probes. A solenoid is used to produce a uniform magnetic field parallel to the discharge axis. The axial changes of the plasma parameters are presented in the range of longitudinal magnetic fields 200 to 600 Gauss at the pressure range 0.3 to 2.1 Torr and discharge currents 5 and 15 mA in argon gas. The experimental results indicate that, as a consequence of the axial ma...
The pulse frequency noise of magnetars and persistent accretion powered pulsars Serim, Danjela; Baykal, Altan; Department of Physics (2021-2-03) In this thesis, the pulse frequency fluctuations of magnetars and six selected persis-tent accreting powered pulsars (PAPPs) are presented. Using the data fromRXTE,XMM-Newton, Chandra, SwiftandFERMIobservatories, the timing noise behav-ior of individual sources on various timescales are examined, depending on the datasampling rate of input frequency measurements. The timing noise amplitudes are an-alyzed via two separate methods, namely∆8andr.m.smethods. The timing noisecharacteristics of both magne...
The diminution of the neutron odd-even effect due to prompt neutron emission in low energy nuclear fission Buyukmumcu, Z; Kildir, M (Springer Science and Business Media LLC, 1997-06-01) Two fissioning systems [U-235(n(th), f) and Cf-252(sf)] have been studied to see the consequence of prompt neutron emission on odd-even effects. Monte Carlo calculations have been carried out for prompt neutron emission. Fragment and product yields have been analyzed by the Wahl Z(p), Model the Method of Differences and Model Independent Calculations. The result of the wash-out effect of prompt neutron emission on the neutron odd-even effect has been shown: however, this was not seen with the protons.
