The 2D Fermi surface of 1st stage PdAl2Cl8 acceptor-type graphite intercalation compounds (GICs) has been investigated using the Shubnikov-de Haas (SdH) effect. One fundamental frequency is observed, the angular variation of which confirms its strongly 2D nature, as previously found through electrical conductivity measurements. The energy spectrum can be described by the 2D band structure model proposed by Blinowski et al. We obtain the following parameter values: intraplane C-C interaction energy gamma_0 = 2.7 eV, Fermi energy E_F = -1.1 eV and carrier density n_SdH= 1.1x10^27 m^-3. Some fewer details are presented on stage 2 and 3 materials.
