摘要：
The three-nucleon (NNN) interaction derived within the chiral effective field theory at the next-to-next-to-leading order ((NLO)-L-2) is regulated with a function depending on the magnitude of the momentum transfer. The regulated NNN interaction is then local in the coordinate space, which is advantageous for some many-body techniques. Matrix elements of the local chiral NNN interaction are evaluated in a three-nucleon basis. Using the ab initio no-core shell model (NCSM) the NNN matrix elements are employed in H-3 and He-4 bound-state calculations.
