Recursion Method for Deriving Energy-Independent Effective Interaction
Kenji Suzuki, Hiroo Kumagai, Ryoji Okamoto +1
The effective-interaction theory has been one of the useful and practical methods for solving nuclear many-body problems based on the shell model. Various approaches have been prop…
Formulation of effective interaction in terms of renormalized vertices and propagators
Kenji Suzuki, Hiroo Kumagai, Masayuki Matsuzaki +1
One of the useful and practical methods for solving quantum-mechanical many-body systems is to recast the full problem into a form of the effective interaction acting within a mode…
Dependence of Nuclear Binding Energies on the Cutoff Momentum of Low-Momentum Nucleon-Nucleon Interaction
S. Fujii, H. Kamada, R. Okamoto +1
Binding energies of ^{3}H, ^{4}He, and ^{16}O are calculated, using low-momentum nucleon-nucleon interactions (V_{low-k}) for a wide range of the cutoff momentum Λ. In addition, si…
Low-momentum nucleon-nucleon interaction and its application to the few-nucleon systems
S. Fujii, E. Epelbaum, H. Kamada +3
Low-momentum nucleon-nucleon interactions are derived within the framework of a unitary-transformation theory, starting with realistic nucleon-nucleon interactions. A cutoff moment…
Shell structures in oxygen isotopes described with modern nucleon-nucleon interactions
S. Fujii, R. Okamoto, K. Suzuki
Shell structures in the N\simeq Z nucleus ^{17}O and the neutron-rich oxygen isotopes ^{23}O and ^{25}O are microscopically described by calculating single-particle energies with m…
Charge-dependent calculations of single-particle energies in nuclei around ^{16}O with modern nucleon-nucleon interactions
S. Fujii, R. Okamoto, K. Suzuki
The binding energies of the ground states and several excited states related to single-particle and -hole states in nuclei around ^{16}O are calculated taking charge dependence int…
