    "abstract": "We estimate four-nucleon force effects between different 4He wave functions\nby calculating the expectation values of four-nucleon potentials which were\nrecently derived within the framework of chiral effective field theory. We find\nthat the four-nucleon force is attractive for the wave functions with a totally\nsymmetric momentum part. The additional binding energy provided by the\nlong-ranged part of the four-nucleon force is of the order of a few hundred\nkeV.",
