Three types of state-to-state dielectronic recombination processes for Be-like i ons Au75+ have been investigated. Based on multi-configuration Hartre e-Foc k-Relativistic and distorted wave approaches, state-to-state dielectronic recomb ination rate coefficients have been calculated at electron temperatures 0.6-10.0 keV. Variations of the coefficient with electron temperature, recombination type s and up-or down-states have also been discussed in detail.

The theoretical study on PuHn+(n=1,2,3) using density functional meth od(B3LYP) shows that PuH+ and PuH2+ can be stable and PuH3+(7Σ-) cannot be stable. Electronic ground sta tes are X7Σ-(PuH+) and X8Σ-(PuH2+),and their force constants and spectroscopic data have bee n worked out.
