N2 - The e+e-→Ds+Ds1(2536)- and e+e-→Ds+Ds2∗(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 Ds1(2536)-→D¯∗0K- and Ds2∗(2573)-→D¯0K- are measured for the first time to be (35.9±4.8±3.5)% and (37.4±3.1±4.6)%, respectively. The e+e-→Ds+Ds1(2536)- and e+e-→Ds+Ds2∗(2573)- cross sections are measured, and a resonant structure at around 4.6 GeV with a width of 50 MeV is observed in both processes with a statistical significance of 7.2σ and 15σ, respectively. The state is observed for the first time in e+e-→Ds+Ds2∗(2573)- and could be the Y(4626) found by the Belle oration in the Ds+Ds1(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.
