    "abstract": "Low-momentum nucleon-nucleon interactions are derived within the framework of\na unitary-transformation theory, starting with realistic nucleon-nucleon\ninteractions. A cutoff momentum Lambda is introduced to specify a border\nbetween the low- and high-momentum spaces. By the Faddeev-Yakubovsky\ncalculations the low-momentum interactions are investigated with respect to the\ndependence of ground-state energies of ^3H and ^4He on the parameter Lambda. It\nis found that we need the momentum cutoff parameter Lambda \u003e= 5 fm^-1 in order\nto reproduce satisfactorily the exact values of the binding energies for ^3H\nand ^4He. The calculation with Lambda =2 fm^-1 recommended by Bogner et al.\nleads to considerable overbinding at least for the few-nucleon systems.",
