Effective three-body interactions in nuclei
arXiv:1005.0900 · doi:10.1209/0295-5075/90/32001
Abstract
It is shown that the three-body forces in the $1f_{7/2}$ shell, for which recently evidence was found on the basis of spectroscopic properties of the Ca isotopes and $N=28$ isotones, can be most naturally explained as an effective interaction due to excluded higher-lying shells, in particular the $2p_{3/2}$ orbit.}
