ABSTRACT: First, strong and weak interactions as short-range should be unified. Except different action ranges their main character is: strong interactions are attraction each other, and weak interactions are mutual repulsion and derive decay. We propose a new method on their unification, whose coupling constants are negative and positive, respectively. Further, we research a figure on the unification of the four basic interactions in three-dimensional space. Second, so far the high energy experiments in the past sixty years have shown that the smallest mass fermions are proton, electron, neutrino and photon, which form the simplest model of particles. These fermions seem to be inseparable truth “atoms” (elements), because further experiments derive particles with bigger mass. They correspond to four interactions, and are also only stable particles. Third, the final simplest theory is based on leptons (e- ) and nucleons (p-n) or (u-d) in quark model with SU(2) symmetry and corresponding Yang-Mills field. Other particles and quark-lepton are their excited states. The simplest interactions and simplified QCD are discussed. Finally, we discuss some possibly developed directions of particle physics, for example, violation of basic principles, and precision and systematization of the simplest model, etc.

ABSTRACT: In this paper, energy positions of the 3s23p4(1D)[nd(2D;2P;2S);ns(2D3/2)], 3s23p4(1S)[nd(2D;2S1/2)], 3s3p5(3P20, 3P10, 3P00)np and 3s23p53d(1P10)ns. Rydberg series from ground state of Ca3+ ion. Calculations are performed with 4 ≤ n ≤ 20 using the Screening Constant by Unit Nuclear Charge (SCUNC). The present results compared well with the experimental data of Ghassan A Alna’washi which are the only available values.
