Ground-state and single-particle energies of nuclei around ^{16}O, ^{40}Ca, and ^{56}Ni from realistic nucleon-nucleon forces
S. Fujii, R. Okamoto, K. Suzuki
We perform ab initio calculations for nuclei around ^{16}O, ^{40}Ca, and ^{56}Ni using realistic nucleon-nucleon forces. In particular, ^{56}Ni is computed as the heaviest nucleus…
Ab initio shell-model calculation for ^{18}O in a restricted no-core model space
S. Fujii, B. R. Barrett
We perform an ab initio shell-model calculation for ^{18}O in a restricted no-core model space, microscopically deriving a two-body effective interaction and introducing a minimal…
Microscopic shell-model description of the exotic nucleus ^{16}C
S. Fujii, T. Mizusaki, T. Otsuka +2
The structure of the neutron-rich carbon nucleus ^{16}C is described by introducing a new microscopic shell model of no-core type. The model space is composed of the 0s, 0p, 1s0d,…
Separability of a Low-Momentum Effective Nucleon-Nucleon Potential
H. Kamada, S. Fujii, E. Uzu +3
A realistic nucleon-nucleon potential is transformed into a low-momentum effective one (LMNN) using the Okubo theory. The separable potentials are converted from the LMNN with a un…
The unitary-model-operator approach to nuclear many-body problems
S. Fujii, R. Okamoto, K. Suzuki
Microscopic nuclear structure calculations have been performed within the framework of the unitary-model-operator approach. Ground-state and single-particle energies are calculated…
Formal Relation among Various Hermitian and non-Hermitian Effective Interactions
R. Okamoto, S. Fujii, K. Suzuki
A general definition of the model-space effective interaction is given. The energy-independent effective hamiltonians derived in a time-independent way are classified systematicall…
