Effect of Tensor Correlations on Single-particle and Collective States
H. Sagawa
We study the effect of tensor correlations on single-particle and collective states within Skyrme Hartree-Fock and RPA model. Firstly, We study the role of tensor interactions in S…
Possible Shape Coexistence and Magnetic Dipole Transitions in C and Ne
H. Sagawa, X. R. Zhou, Toshio Suzuki +1
Magnetic dipole(M1) transitions of N=11 nuclei, C and Ne are investigated by using shell model and deformed Skyrme Hartree-Fock+blocked BCS wave functions. Shell mode…
Pairing correlations and effective mass
Satoshi Yoshida, Hiroyuki Sagawa
We study the effect of effective mass on pairing correlations in the ground states of superfluid nuclei Sn and Sn. Various parameter sets of Skyrme interactions and…
Strong dineutron correlation in 8He and 18C
K. Hagino, N. Takahashi, H. Sagawa
We study the spatial structure of four valence neutrons in the ground state of He and C nuclei using a core+4 model. For this purpose, we employ a density-dependent c…
Effective pairing interactions with isospin density dependence
J. Margueron, H. Sagawa, K. Hagino
We perform Hartree-Fock-Bogoliubov (HFB) calculations for semi-magic Calcium, Nickel, Tin and Lead isotopes and =20, 28, 50 and 82 isotones using density-dependent pairing inter…
BCS-BEC crossover of neutron pairs in symmetric and asymmetric nuclear matter
J. Margueron, Hiroyuki Sagawa, Kouichi Hagino
We propose new types of density dependent contact pairing interaction which reproduce the pairing gaps in symmetric and neutron matter obtained by a microscopic treatment based on…
