The interaction energies of a hydrogen atom, H, which crosses the liquid vapour interface of 4He and 3He are calculated in two different approaches. Liquid helium is considered non-deformable in the first approach while in the second one the H atom is supposed to be in a rigid cavity (bubble) while crossing the interface. Bound states are found for H outside liquid 4He only. The implications of the results for obtaining stable atomic H at low temperature are discussed.
