本文描述了计算等离子体激发和电离的计算机代码GALAXY，包括辐射场的影响，无论是入射到等离子体上还是通过线的光学深度在内部产生。在没有用户提供的原子数据的情况下，GALAXY使用简单的标度氢表达式计算能级以及连接能级的电子碰撞率和辐射率。对于相对高度电离的系统，发现这种方法足够精确，可用于研究高功率激光产生的等离子体。
In this paper we describe the computer code GALAXY which calculates the excitation and ionization of a plasma, including the effect of the radiation field, whether incident on the plasma or generated internally through the optical depth of the lines. In the absence of atomic data provided by the user, GALAXY calculates energy levels and the electron collisional and radiative rates which link them, using simple scaled-hydrogenic expressions. For relatively highly ionized systems this approach is found to be sufficiently accurate to be useful in studies of high-power laser-produced plasmas.
