摘要: We report the plasma screening effect on first ionization potential (IP) and [He]2s2 (1S0)→[He]2s2p/2s3p allowed (P11) inter-combination transitions (P31) in some selected Be-like ions. In addition, we investigate spectral properties of [Ne]3s (2S1/2)→[Ne]np (2P1/2 P23/2 for n = 3, 4) Ca X Fe XVI ions (Na I isoelectronic sequence) [He]3s(2S1/2)→[He]np (2P1/2 n = 2, 3) Li, B II, N IV (Li under environment. The state-of-the-art relativistic coupled cluster calculations using Debye model electron-nucleus interaction show that (a) decreases sharply with increasing strength (b) gap between [He]2s2 (1S0)→[He]2s2p(1,3P1) energy levels increases nuclear charge. It is found [He]2s2 (1S0)→2s3p (1,3P1) transition uniformly other words,...
