2.THE CALCULATION OF SPIN ENERGY LEVEL AND WAVE FUNCTION OF ELECTRON FOR Cr~(3+)IN K_3[Cr(CN)_6]
3.We obtain a new quark potential from the effective dilaton-gluon-coupling inspired by superstring theory, and by using this static potential, we explore the mechanism of quark confinement through calculations of the spin-average energy levels, the widths of the leptonic decays and radiative transitions for heavy quarkonium. The obtained results are compared with that of the Cornell potenial.
6.By using the rare-earth spectroscopy theory, the coulomb interactions between f electrons and d electron of 4 f N-15d configurations of rare earth are calculated. It is found that the energy of spin-allowed levels is higher than that of spin-forbidden levels for heavy lanthanide ions(N>7), and the energy difference between the spin-allowed and the spin-forbidden levels decreases with the increase in N.
