Pd 3d5/2 binding energy values [1].

Pd 3d5/2 - Pd 3d3/2 splitting:  5.31 +/- 0.12 eV (ave. of 8 Ref.), [2] specifies a splitting of 5.26 eV. Reference spectrum of the metal shows a splitting of 5.29 eV (see spectrum below).
Pd 3p3/2: 533 eV
Pd 3p1/2: 560 eV
Pd 3s: 671 eV
Pd 4p: 52 eV
Pd 4s: 88 eV

A) PdO is reduced relatively rapidly by X-rays. Take steps to minimize X-ray exposure during acquisition.

B) Some references quote B.E. values for PdO2, however PdO is the only well characterized oxide of palladium.

C) For a sputter cleaned Pd metal surface a Pd 3d5/2 lineshape of LA(1.9,7,2) and FWHM of 0.68 eV (10 eV pass energy) or 0.71 eV (20 eV pass energy) was found.
