Spherical to deformed shape transition in the nucleon-pair shell model
Y. Lei, S. Pittel, G. J. Fu +1
A study of the shape transition from spherical to axially deformed nuclei in the even Ce isotopes using the nucleon-pair approximation of the shell model is reported. As long as th…
Many-body Systems Interacting via a Two-body Random Ensemble: average energy of each angular momentum
Y. M. Zhao, A. Arima, N. Yoshinaga
In this paper, we discuss the regularities of energy of each angular momentum averaged over all the states for a fixed angular momentum (denoted as 's) in many-body…
Many-body Systems Interacting via a Two-body Random Ensemble (I): Angular Momentum distribution in the ground states
Y. M. Zhao, A. Arima, N. Yoshinaga
In this paper, we discuss the angular momentum distribution in the ground states of many-body systems interacting via a two-body random ensemble. Beginning with a few simple exampl…
A simple approach to the angular momentum distribution in the ground states of many-body systems
Y. M. Zhao, A. Arima, N. Yoshinaga
We propose a simple approach to predict the angular momentum I ground state (I g.s.) probabilities of many-body systems that does not require the diagonalization of hamiltonians wi…
Towards understanding the probability of ground states in even-even many-body systems
Y. M. Zhao, A. Arima
For single- shells with and 11/2, we relate the large probability of ground states to the largest (smallest) coefficients $A^{J…
