N2 - It has recently been demonstrated that pentacene can serve as protection layer for graphene on SiCp reserving the unique E(k) band dispersion after exposure to atmosphere and subsequent annealingin vacuum.We confirm the stability of the ideal graphene band dispersion but without any protectionlayer.We demonstrate this by angle-resolved photoemission for graphene on Ni (111) intercalated by a Au monolayer. Exposure to air does not carbidize or oxidize the Ni substrate or open an apparentgap in the graphene. Its doping state is not affected and the Rashba-type spin-orbit effect on the graphene state is preserved.
