Abstract Eigenquantum defects μ_α and transformation matrix U_iα of La⁺ are calculated from the first principles by relativistic multichannel theory, and dipole matrix elements D_α are obtained by fitting the experimental spectra. With these parameters, ionic autoionization spectra of lanthanum via an intermediate state (Xe)5d6d¹P₁ of La⁺ in the energy region of 90650-91500cm^-1 are calculated within the framework of multichannel quantum defect theory. Our calculated spectra are in general agreement with the experimental data.
