Dielectronic Recombination Process In Laser Produced Plasmas Of (Xe,Gd,Dy,Au)

The dielectronic recombination (DR) is a main process in the course of electron-ion collision. At moderate (high) electron temperature and low (moderate) -electron density, it is dominant in keeping the balance of ionization and population of upper configuration ions. The paper gives the results of the total DR coefficients of Ni-like, Cu-like, Zn-like in the laser produced plasmas for (Xe,Gd,Dy,Au) and the DR rate coefficients of state-to-state with the change of electron temperature , as well as the relative auto-ionization rate coefficients Aa, radiative decay rate coefficients Ar, potential of ionization , intensity ratio of dielctronic satellite in the model (spin-orbit -split Array, SOSA). We analyze the main factor which effect DR coefficients with the. change of electron temperature and the rule which Ar and Aa change with the principal quantum numbers and spectator electrons. They are useful paramaters in the research of high-Z materials of laser- produced plasmas.At the same time, we calculate the charactical paramaters (Wave-length, FWHM, intensity of array) of the transition sub-array which is included in the process of dielectronic recombination. For example Au plasmas, M-band spectum, intensity of sub-ayyay, 3d-4f and 3d-5f transitions array of Au are analyzed comparing with experiment. These may provide a great number of atomic structure paramaters. For the necessary of obersving spectrum, the three-body recombination,radiative recombination and dielectronic recombination coefficients are calculated in some range of electron density(ne=1.0x1020cm-3,6.0xl020cm-3,1.4xl021cm-3, 1.0xl022cm-3andl.7xl022cm-3) with the change of electron temperature in the ( non-local-thermodynamic-equilibrium,Non-LTE) model at the condition of H-like approximation. The total recombination coefficients are calculated with the change of electron temperature. Making use of the ratio of the relavant population of ionization stage, the fractional population of ionization stage is calculated with the change of electron temperature. At last, the charge -state distribution for gold (Au) plasmas at some electron temperature and some electron density is calculated. It is very important for diagnosing the plasmas of Au in the laboratory.
