We report a study of the decay D0 → K¯⁰π^–e⁺ν_e based on a sample of 2.93 fb^–1 e⁺e^– annihilation data collected at the center-of-mass energy of 3.773 GeV with the BESIII detector at the BEPCII collider. The total branching fraction is determined to be B(D⁰ → K¯⁰π^–e⁺ν_e) = (1.434 ± 0.029(stat.) ± 0.032(syst.))%, which is the most precise to date. According to a detailed analysis of the involved dynamics, we find this decay is dominated with the K*(892)^– contribution and present an improved measurement of its branching fraction to be B(D⁰ → K*(892)^–e⁺ν_e) = (2.033 ± 0.046(stat.) ± 0.047 (syst.))%. We further access their hadronic form-factor ratios for the first time as r V = V ( 0 ) / A 1 (0) = 1.46 ± 0.07(stat.) ± 0.02(syst.) and r₂ = A₂(0)/A₁(0) = 0.67 ± 0.06(stat.) ± 0.01(syst.). In addition, we observe a significant K¯⁰π^– S-wave component accounting for (5.51 ± 0.97(stat.) ± 0.62(syst.))% of the total decay rate.
