## Abstract Let us consider a solution __f__(__x__,__v__,__t__)Ο΅__L__^1^(ℝ^2N^ Γ— [0,__T__]) of the kinetic equation equation image where |__v__|^Ξ±+1^ __f__~o~,|__v__|^Ξ±^ __Ο΅L__^1^ (ℝ__2N__ Γ— [0, __T__]) for some Ξ±< 0. We prove that __f__ has a higher moment than what is expected. Namely, for any b
