【 摘 要 】

A collisional-radiative model based on detailed level approach is developed to investigate the population kinetics of non-local thermodynamic equilibrium (NLTE) carbon plasmas. Present model is used to diagnose a recent measurement for average ionization degree of carbon plasmas at 0.2 g/cm3[G. Gregori et al., Phys. Rev. Lett. 101, 045003 (2008)]. Physical factors which may influence the population kinetics are investigated in detail and it indicates that the high temperature radiative field plays an important role on the ionization balance.
