Diagnosing the lightning plasma temperature based on the collisional-radiative model

摘要: Energy levels, transition probabilities, collision sections, and excitation rate coefficients of NII ion have been calculated using Flexible Atomic Code, which is based on the multiconfiguration Dirac–Fock method. The ratios line intensity, I567.96 nm/I500.52 nm, where 567.96 500.52 nm are two strong spectral lines from core current channel lightning, by collisional-radiative model, in intensity proportional to ground state excited probability high low state. temperatures six lightning plasma channels were then obtained, they consistent with obtained diagnosing actual spectrum multispectral
