The present study includes the preparation of Sn xBa4Ca andYnBa5Cun+5O compounds with (x = 3, 4, 5, 6, 7) and (n=3, 5, 7) by solid state reaction (SSR) method. The study was to conclude the erconductor behavior of both compounds. The prepared samples were analyzed by Meissner effect primary, and the excess oxygen content was measured by using Iodomertric titration method.
The concept of q-deformation has found many important applications in a variety of fields in physics, such as quantum optics, atomic physics, solid state physics,nuclear physics and cosmology. This has motivated its extension to many well-established other concepts such as coherent states well-known in quantum optics. On the other hand, the interpretation of the physical meaning of the q-deformation remains an outstanding problem.The present work is an attempt to apply the concept of q-deformed coherent states to solve this interpretation problem.
The objectives of the present study were to measure the level of the radioactivity Al-Dora refinery and surrounding area. The study includes:
