摘要
The excited states of S+14 ion in (1SnS) states of n (2, 3, 4 and 5) are studied in singlet and triplet states (1S, 3S). This study focuses on studying expectation values of energies (potential (V), kinetic (T), attraction (Ven), repulsion (Vee) and total energy (E)) for S+14 ion in the states (1s 2s, 1s 3s, 1s 4s, 1s 5s). The study also examines some radial atomic properties as expectation values for one electron rm1, inter particle expectation value rm12 and analyses one-particle radial density functions D(r1) using Hartree-Fock wave function for these systems. This system consists of two electrons, one electron is in (1S) state (K-shell) and the second electron is in shells (L, M, N, O) (nS) states. In this paper the atomic units are used and all the atomic properties are normalised to unity. All the results were calculated by the software (MATHCAD 2001i).
