According to the multichannel quantum defect theory (MQDT), we were engaged in the theoretical analysis for the J=0 even-parity and odd-parity states of the argon atom. For two Rydberg series3p^5 (2p_3/2~0)np,3p^5(2P_1/2~0)np anp 3p^5(2P_3/2~0)nd, 3p^5(2P_1/2~0)ns, we have determined the MQDT parameters by fitting the experimental energy level data and the experimental value of oscillator stregth in the discrete states. With these parameters as input, according to the basic equation of MQDT, we have obtained the Lu-Fano plots, the energy levels of all discrete states and the mixing coefficients of the channels, and predicted the autoionization resonance structure.
