A cutoff momentum L is introduced to specify aborder between the low- and high-momentum spaces. By Faddeev-Yakubovsky calculations the lowmomentuminteractions are investigated with respect to the dependence of ground-state energies of 3H and 4Heon the parameter L. It is found that we need the momentum cutoff parameter Lù5 fm−1 in order to reproducesatisfactorily the exact values of the binding energies for 3H and 4He. The calculation with L=2 fm−1 recommendedby Bogner et al. leads to considerable overbinding at least for few-nucleon systems.}, pages = {024003-1--024003-8}, title = {Low-momentum nucleon-nucleon interaction and its application to few-nucleon systems}, volume = {70}, year = {2004}, yomi = {カマダ, ヒロユキ} }
