    Abstract: The present work deals with an ab initio calculation of total energies of the doubly excited np2, nd2 and nf2 states in the helium-like systems. These total energies are calculated in the framework of the variationnal procedure of the Screening constant by unit nuclear charge (SCUNC) formalism. In the present work, a new correlated wave function is... Show More

    Abstract: In 1960 Gell-Mann completed the «Particle Zoo» with a picture simulating a 3-dimensional model: Spin, Strangeness and an oblique incident charge with 3 investigated Quarks constructed in 10 Baryons. Until now the CERN scientists have found 61 elementary particles, but only 17 Fundamental particles are listed in a brick box as «Standard model». But ... Show More

    Abstract: In statistics it is important to know the method of analysing data. The study looked at parametric tests with a special focus on the three t-tests. In this paper, the researcher provide a brief review of commonly used three t-tests namely an independent sample t-test, dependent sample-test and one sample t-test. The researcher has presented the for... Show More

    Abstract: We report accurate energies of the 3 (2,0,+) n 1De, 1Ge, 3F°, 3 (0, 2,+) n 1De, 3 (1,1,+) n 3De, 3Pe, 3Fe, 3 (-1,1,+) n 3Pe, and 3 (1,1,+) n 1D°, 1F°, series of He- like ions using the Screening constant by unit nuclear charge method. It is shown that the angular correlation quantum number K is effectively related to the cosinus of the angle be... Show More

    Abstract: The finding of the solution of the wave equation, formulated as the Cauchy problem, does not exhaust all possibilities of the theory. The attempt to examine that one by admitting that the time is an imaginary value is made. So the new curvilinear coordinates, named hyperbolic, are introduced in consideration. They allow for hyperbolic equations ... Show More
