Low-momentum interaction in few-nucleon systems
Low-momentum interaction in few-nucleon systems
The effective low-momentum interaction Vlowk is applied to three- and four-nucleon systems. We investigate the 3H, 3He and 4He binding energies for a wide range of the momentum cutoffs. By construction, all low-energy two-body observables are cutoff-independent, and therefore, any cutoff dependence is due to missing three-body or higher-body forces. …
