Nuclear prolate-shape dominance with the Woods-Saxon potential
S. Takahara, N. Tajima, Y. R. Shimizu
We study the prolate-shape predominance of the nuclear ground-state deformation by calculating the masses of more than two thousand even-even nuclei using the Strutinsky method, mo…
Method to circumvent the neutron gas problem in the BCS treatment for nuclei far from stability
Toshiya Ono, Yoshifumi R. Shimizu, Naoki Tajima +1
Extending the Kruppa's prescription for the continuum level density, we have recently improved the BCS method with seniority-type pairing force in such a way that the effects of di…
Improved microscopic-macroscopic approach incorporating the effects of continuum states
Naoki Tajima, Yoshifumi R. Shimizu, Satoshi Takahara
The Woods-Saxon-Strutinsky method (the microscopic-macroscopic method) combined with Kruppa's prescription for positive energy levels, which is necessary to treat neutron rich nucl…
Extended RPA with ground-state correlations in a solvable model
S. Takahara, M. Tohyama, P. Schuck
The ground states and excited states of the Lipkin model hamiltonian are calculated using a new theoretical approach which has been derived from an extended time-dependent Hartree-…
Relation between the density-matrix theory and the pairing theory
Mitsuru Tohyama, Satoshi Takahara
The time-dependent density-matrix theory (TDDM) gives a correlated ground state as a stationary solution of the time-dependent equations for one-body and two-body density matrices.…
Extended RPA with ground-state correlations
M. Tohyama, S. Takahara, P. Schuck
We propose a time-independent method for finding a correlated ground state of an extended time-dependent Hartree-Fock theory, known as the time-dependent density-matrix theory (TDD…
