In this paper we have analysed the spectrum of Gall by means of multichannel quantum-defect theory (MQDT). Here the MQDT parameters for even-parity J = 0,1,2,3 and odd-parity J=1,2 bound levels involving three limits are determined through a fit of the calculated results to experimental data. The unknown energy levels of eleven Rydberg series are predicted by using these optinum parameters. The interaction between these series are discussed. The predicted energy values are in good agreement with the experimental data from ref. [1] .
