The e^+e^- Dₛ^+Dₒ₁ (2536) ^- and e^+e^- Dₛ^+D^*ₒ₂ (2573) ^- processes are studied using data samples collected with the BESIII detector at center-of-mass energies from 4. 530 to 4. 946~GeV. The absolute branching fractions of Dₒ₁ (2536) ^- D^*0K^- and Dₒ₂^* (2573) ^- D⁰K^- are measured for the first time to be (35. 9 4. 8 3. 5) \% and (37. 4 3. 1 4. 6) \%, respectively. The measurements are in tension with predictions based on the assumption that the Dₒ₁ (2536) and Dₒ₂^* (2573) are dominated by a bare cs component. The e^+e^- Dₛ^+Dₒ₁ (2536) ^- and e^+e^- Dₛ^+D^*ₒ₂ (2573) ^- cross sections are measured, and a resonant structure at around 4. 6~GeV with a width of 50~MeV is observed for the first time with a statistical significance of 15 in the e^+e^- Dₛ^+D^*ₒ₂ (2573) ^- process. It could be the Y (4626) found by the Belle collaboration in the Dₛ^+Dₒ₁ (2536) ^- final state, since they have similar masses and widths. There is also evidence for a structure at around 4. 75~GeV in both processes.
