Description: Author(s): G. J. Fu, J. J. Shen, Y. M. Zhao, and A. Arima In this paper we study low-lying states of atomic nuclei with random interactions, within the framework of the nuclear shell model. The distributions of R 6 versus R 4 (where R I ≡ E I 1 + / E 2 1 + ), empirical proton-neutron interaction, and charge radius are investigated by using a two-body random ensemble. Th... [Phys. Rev.

Description: Author(s): G. J. Fu, J. J. Shen, Y. M. Zhao, and A. Arima T =0 states of 96 Cd, 94 Ag, and 92 Pd are studied by using the nucleon-pair approximation and the JUN45 interaction for the p 1/2 p 3/2 f 5/2 g 9/2 shell. We focus on the approximation of isoscalar spin-aligned pairs in a single- j 1 g 9/2 shell. Configurations associated with the 2 p 1/2 and 2 p 3/2 orbits are inve... [Phys. Rev.

Description: Author(s): J. J. Shen, Y. M. Zhao, A. Arima, and N. Yoshinaga We study extrapolation approaches to evaluate energies of low-lying states for nuclei in the sd and pf shells, by sorting the diagonal matrix elements of the nuclear shell-model Hamiltonian. We introduce an extrapolation method with perturbation and apply our new method to predict both low-lying sta... [Phys. Rev. C 83, 044322] Published Wed Apr 27, 2011

Description: Author(s): J. J. Shen, Y. M. Zhao, and A. Arima We suggest a perturbation method for obtaining the lowest eigenvalues of the nuclear-shell -model Hamiltonian. We introduce a “cutoff” based on the features of the nuclear-shell-model Hamiltonian matrices. Our new method is exemplified by a few realistic nuclei. Overlaps between the wave functions o... [Phys.

The isoscalar proton-neutron interactions of the shell model results are found to be consistent with those empirically extracted by the double difference of binding energies. We point out that t...
