We study perturbativeness of chiral nuclear forces in the 3P0 channel.In previous works,the focus has been on the one-pion exchange,and the applicable window of perturbative pion exchanges has been shown to span from the threshold to center-of-mass momentum k ≌ 180 MeV.We will examine,instead,whether the cancellation of short-and long-range parts can sufficiently soften the 3po chiral force to make it more amenable to perturbation theory.The result is encouraging,as the combined 3P0force is shown to be perturbative up to k ≌ 280 MeV,covering many nuclear-structure calculations.
