DIELECTRONIC RECOMBINATION IN LASER PRODUCED HIGHZ PLASMA

The dielectronic recombination in average atom model has been studied by coupling the hydrodynamic equations with nonlocal thermalequilibrium electron population equtions,the effect of dielectronic recombination on the high power laser produced Au plasma has been investigated. It has been shown that in comparison with radiative and threebody recombination process the dielectronic recombination is the dominant one in a part of coroa region of high temperature and low density Au plasma produced by high power laser．
