Abstract: In this paper, we have applied the complex rotation method to the calculations energies of the ground state (1s22s) 2S and the low-lying excited (1s2ns)2S states with n = 3, 4 and 5; of lithium and its isoelectronic series. For the ground state, the calculations were made up to Z = 20 and for the low-lying excited states up to Z = 10. These energies calculations were made using new special forms of Hylleraas-type wave functions designed by combining incomplete radial hydrogenic wave functions and Hylleraas-type wave functions. Using a numerical calculation program, the values of the resonance energies are calculated. Our results are compared with the results of ab-initio calculations using Hylleraas type wave functions and with semi-empirical results by Screening Constant by Unit Nuclear Charge (SCUNC) formalism. Analysis of the present results is achieved by calculating the ratio and the difference between our values and those of other authors. The results obtained are in good agreement with those of the theoretical methods available in the literature. This agreement shows the adequacy of our wave function with small bases to satisfactorily describe the ground state and the low-lying excited states of the three-electron atomic systems.

Abstract: We have presented an elegant high energy quantum problem, namely, the full Dirac oscillator under axial magnetic field with its full solution. We have found the energy spectrum which is rich and at the same time has a novel structure. The quantized energy levels show coupling of the oscillator frequency with the Larmor frequency in the 2D surface where the electrons under consideration follow a 2D oscillator. The axis in which magnetic field is pointed, the electrons follow a 1D oscillator. There is also coupling between spin and orbital motion and also a coupling between a resultant effect of orbital and spin motion with Larmor precession.

Abstract: In this research the interpretation of Suzaku spectral observation of Fe kα emission line from Sigma Gem system was carried out. Sigma Gem was observed using Suzaku satellite with observation ID 402033010 at an exposure time of 142. 82 ks. Spectral analysis of all observations was performed using XSPEC version 12.8. We used version 2.00 of the standard Suzaku pipeline products and the HEA Soft version 6.16 for our analysis of data. We adopted a 250′′ radius to extract all events for the XIS detector to produce the source spectra, but we adjusted the 250′′ radius slightly where it overlaps with the calibration sources at the corners, to avoid capturing source background light. Modeling the spectrum using either power law or bremsstrahlung model with three Gaussian line for the 6.4 keV, He–like 6.7 keV, H–like 7.0 keV, Fe Kα emission lines shows that the 6.4 keV, 7.0 keV lines and absorption in both full and partial covering matter could not be measured in all the sources. We were able to resolve the three-narrow iron kα emission lines with different ionization states, which constraints the Sigma Gem emission models. The iron K- line complex was clearly resolved into three individual peaks at 6.41 keV, 6.7 keV and 7.0 keV. The light curve shows that the Sigma Gem was at a quiescent state at the point of observation and The light curve shows a considerable quiescent behavior of the source of the point of observation showing the source is not flaring.

Law of Physics 20th-Century Scientists Overlooked (Part 3): Noninteraction Mass-to-Energy Conversion

Abstract: Two situations are contrasted. First is a scenario in which a force (an interaction) is applied to a mass particle (or object) in order to increase its speed. When this particle is accelerated it gains kinetic energy. By means of electromagnetic interaction or repeated collisional impact, the mass particle may acquire ever greater speed and ever greater kinetic energy. But, by such means, the particle can never ever attain lightspeed. However, Nature has a noninteraction mechanism by which mass is compelled to travel at lightspeed and in doing so, the mass undergoes conversion to pure photonic energy. Under this noninteraction second scenario, the mass merely rests on the surface of a slowly collapsing gravitating body while the surface inflow of the space medium increases to its ultimate limit. With the aid of a schematic energy triangle, it is shown why lightspeed is unattainable under scenario #1; whereas lightspeed IS attainable under scenario #2 and in the process a total conversion of mass to energy occurs. Presented is a remarkably natural 100-percent conversion process that requires no new force, no new particle, and no radically new physics. Nor does it require changing any existing force. If theorists of the 20th century had recognized this mass-to-energy conversion mechanism, their understanding of gravitational collapse would have been radically different —it would have been perfectly natural.
