Abstract

We discuss recent developments in electromagnetic production of kaon of a nucleon. A detailed chronological progress in this field is presented. Special attention is given for the isobar model which is not only useful for explaining experimental data, but also important in the nuclear application. Other applications, such as in the quest of "missing resonances" and in the investigation of the hadronic as well as electromagnetic baryon form factors, are also discussed. We also touch on the latest achievements in Regge models and multipole analyses of this process. The basic formalism required for numerical calculations is also thoroughly presented.

Abstract

The non-orthogonal Laguerre L2 basis has been applied in the intermediate energy region (30, 40 and 50 eV) for the electron impact elastic and excitation of 21S, 21P, 23S and 23P states of helium. Differential and integrated cross sections are calculated and compared with recent experiments. The results for each case are discussed and compared with other calculation. It is found that the results agree quite well with experiments and with the other results.

Abstract

Lasing performance of Nd3+-fluoroaluminate glasses has been predicted with the help of laser parameters for the transitions 4F3/2 → 4I9/2, 4F3/2 → 4I11/2 and 4F3/2 → 4I13/2 in the near infrared region. Judd-Ofelt parameters have been used for the calculations of different laser parameters. Analysis yielded some of the important spectroscopic parameters, namely radiative transition probabilities, radiative lifetimes and fluorescence branching ratios. The branching ratios for 4F3/2 → 4I13/2 and their emission to Exited State Absorption (ESA) intensity ratios are higher at the glasses containing Pb2+ ion while their radiative lifetime shows the opposite trend. The overall results reported here showed that Nd3+doped fluoroaluminate glasses containing Pb2+ is a promising active laser material with high refraction index.

Abstract

TiO2:Co thin films were grown on Si substrates by Metalorganic Chemical Vapor Deposition (MOCVD) technique using titanium(IV)isopropoxide and tris(2,2,6,6-tetramethyl-3,5-heptanedionato)cobalt (III), and oxygen gas. The films grown at temperature of 450 oC were crystalline having a rutile structure with (002) orientation. Based on Energy Dispersive Spectroscope (EDS) analysis, Co content in TiO2 was 1.83% and films exhibit ferromagnetic properties at room temperature. Hysteresis curves obtained from Vibrating Sample Magnetometer (VSM) measurement have coercive and saturation magnetic fields of 130 Oe and 2.1 emu/cm3, respectively. Application of TiO2:Co as injection material in spintronic device with TiO2:Co/Si/TiO2:Co structure was investigated. The effect of polarized spin injection (magnetoresistance phenomenon) was observed from the current-voltage characteristics of the device.

Abstract

The Bi4Ti3O12 powder was synthesized using hydrothermal method from Bi2O3/TiO2 and Bi(OH)3/TiO2 as starting materials and NaOH as mineralizer. Characterization of the obtained powder was carried out using X-Ray Diffraction (XRD) and Fourier Transform Infrared (FTIR). High purity of Bi4Ti3O12 powder was obtained from reaction at 240 °C, 72 hours and NaOH of 3 M for both starting materials. The obtained diffraction patterns were similar with the standard pattern (PDF, no. 35-0795). The FTIR spectrum revealed two absorption peaks at 587 and 827 cm-1, which are characterictic absorbtion of octahedral TiO6 in Bi4Ti3O12 structure.
