激光靶耦合中的部分角量子数平均原子模型

A Partial l-splitting Average Atomic Model in Laser-target Coupling

在一维平面非平衡多群辐射输运激光靶耦合总体程序RDMG角量子数平均原子模型的基础上,针对程序在计算如Au等高Z元素时,所需计算能级太多,计算量大的问题,合理的提出了只在部分能级考虑角量子数,其它能级考虑主量子数的部分角量子数平均原子模型.对比了新旧模型的数值模拟结果,结果显示,新模型得到了与原模型符合的很好的物理图像,同时计算时间由于计算能级数的减少而大大降低.

A partial l-splitting average atomic model is presented, in which only energy levels that mainly contribute to the X-ray emission are opened to l-splitting. Compared with an all l-splitting average atomic model, the partial l- splitting average atomic model obtains same results, such as electron temperature, plasma density, X-ray spectrum and so on, and saves a large amount of CPU time due to the decreasing of energy level number.
