Resumo

We analyse the renormalization of the of two-nucleon interaction with multiple subtractions in peripheral waves considering two chiral forces at N3LO. Phase shifts at low energies are then computed with several subtraction points below mu = 10fm(-1). We show that for most peripheral waves the phase shifts have nearly no dependence on the renormalization scale. In two cases the phase shifts converge slowly as the renormalization scale approaches mu= 1fm(-1) and in one case the phase shifts presented oscillations with respect to the subtraction point mu.
