The Energy-Weighted and Non Energy-Weighted Gamow-Teller Sum Rules in Relativistic Random Phase Approximation
Haruki Kurasawa, Toshio Suzuki
The non energy-weighted Gamow-Teller(GT) sum rule is satisfied in relativistic models, when all nuclear density-dependent terms, including Pauli blocking terms from nucleon-antinuc…
Quantum Markov Process on a Lattice
T. Hashimoto, M. Horibe, A. Hayashi
We develop a systematic description of Weyl and Fano operators on a lattice phase space. Introducing the so-called ghost variable even on an odd lattice, odd and even lattices can…
The Gamow-Teller Resonance in Finite Nuclei in the Relativistic Random Phase Approximation
Zhong-Yu Ma, Bao-Qiu Chen, Nguyen Van Giai +1
Gamow-Teller(GT) resonances in finite nuclei are studied in a fully consistent relativistic random phase approximation (RPA) framework. A relativistic form of the Landau-Migdal con…
Hartree-Fock+BCS approach to unstable nuclei with the Skyrme force
Naoki Tajima
We reanalyze the results of our extensive Hartree-Fock + BCS calculation from new points of view paying attention to the properties of unstable nuclei. The calculation has been don…
Canonical-basis solution of the Hartree-Fock-Bogoliubov equation on three-dimensional Cartesian mesh
Naoki Tajima
A method is presented to obtain the canonical-form solutions of the HFB equation for atomic nuclei with zero-range interactions like the Skyrme force. It is appropriate to describe…
The Gamow-Teller States in Relativistic Nuclear Models
Haruki Kurasawa, Toshio Suzuki, Nguyen Van Giai
The Gamow-Teller(GT) states are investigated in relativistic models. The Landau-Migdal(LM) parameter is introduced in the Lagrangian as a contact term with the pseudo-vector coupli…
