UPdAl is an attractive material because of the coexistence of the antiferromagnetic order below 
= 14.5 K and superconductivity below 
= 2 K. In order to discuss the coupling between magnetism and superconductivity by resonant magnetic X-ray scattering (RMXS), nature of the resonance at each absorption edge should be clarified before the measurements across . Therefore we performed RMXS study from U 
to 
edge at 
. In addition to a huge resonance at -edge, we observed a resonant feature at 
-edge which corresponds to the transition from 
to 
orbitals, while resonance at -edge and 
-edge is rather small.

We use the full-potential linearlized augumented plane wave method in the LDA+U scheme, and introduce the lattice distortion as inputs of the calculation. We obtain finite intensity on magnetic superlattice spots by taking account of the spin-orbit interaction. We also calculate the RXS intensity on orbital superlattice spots. It is found that the intensity increases with increasing Jahn-Teller distortion.
