We show that the slow viscoelastic response of a foam is that of a power-lawfluid with a terminal relaxation. Investigations of the foam mechanics in creepand recovery tests reveal that the power-law contribution is fully reversible,indicative of a delayed elastic response. We demonstrate how this contributionfully accounts for the non-Maxwellian features observed in all tests, probingthe linear mechanical response function. The associated power-law spectrum isconsistent with soft glassy rheology of systems with mechanical noisetemperatures just above the glass transition [Fielding et al., J.Rheol. 44,323(2000)] and originates from a combination of superdiffusive bubble dynamicsand stress diffusion, as recently evidenced in simulations of coarsening foam[Hwang et al., Nat.Mater. 15, 1031 (2016)].
