The Real

    X-ray emission contains some of the gaseous properties is produced when the particles of the solar wind strike the atmosphere of comet ISON and PanSTARRS Comets. The data collected with NASA Chandra X-ray Observatory of the two comets, C/2012 S1 (also known as Comet ISON) and C/2011 S4 (Comet PanSTARRS) are used in this study.    The real abundance of the observed X-ray spectrum elements has been extracted by a new simple mathematic model. The study found some physical properties of these elements in the comet’s gas such as a relationship between the abundance with emitted energy. The elements that have emission energy (2500-6800) eV, have abundance (0.1-0.15) %, while the elements that have emission energy (850-2500) eV and (6800-9250) eV have abundance (0.2-0.3) %.    The relation between interacted energy and atomic number is form two sets.  The interacted energy of each element is increased as the atomic number increased. This case has been seen in both comets

AbstractThe spatial dependence of the band-gap light-emission energy of AlxGa1-xN alloys at composition 0≤ × ≤1 was studied via deep UV-photoluminescence (PL) and Raman microscopy. The data were acquired in a random fashion from an area of ∼ 1mm2 on the sample at steps of ∼1 νm - 200 νm utilizing the 244 nm laser line of probing spot size ∼300 nm radius. Our study indicates that the PL emission energy exhibits random type variations depending on locality: the alloys of composition x=0.12, x=0.22, and x=0.70 exhibit variations of ∼ 10 meV, 30 meV, and 25 meV respectively. The PL of the pure GaN exhibits no spatial dependence while the alloy of x=0.50 exhibits a variation around ∼ 45 meV. Moreover, the functional dependence of the band-gap Eg, on the composition was found to be Eg(x)=3.4(1-x)+6.2x-1.2x(1-x) from which the compositional variation, δx, can be computed for a given variation in the PL emission energy after accounting for the stress effect in the alloys.
