We have investigated resonant tunneling experiments through a quantum antidot in the quantum Hall regime.
When the two edge states with different spins of the lowest Landau level are localized around an antidot conductance exhibits the paired $h/2e$
Aharonov-Bohm oscillations.
Using a tilted magnetic field technique we observed evolution of the oscillation with the Zeeman energy.
A concomitant change is observed in the conduction spectra at finite source-drain bias.
These results are interpreted by the energy spacings between the single particle states with the same spin and the Zeeman splitting.
