Graphical Method for Effective Interaction with a New Vertex Function
K. Suzuki, R. Okamoto, H. Kumagai +1
Introducing a new vertex function, Z(E), of an energy variable E, we derive a new equation for the effective interaction. The equation is obtained by replacing the Q-box in the Kre…
A new solution for effective interaction
R. Okamoto, K. Suzuki, H. Kumagai +1
A new method is given for the model-space effective interaction. Introducing a new operator in place of the Q-box in the Krenciglowa-Kuo (KK) method, we derive a new equation for t…
Lowest eigenvalue of the nuclear shell model Hamiltonian
J. J. Shen, Y. M. Zhao, A. Arima
In this paper we investigate regular patterns of matrix elements of the nuclear shell model Hamiltonian , by sorting the diagonal matrix elements from the smaller to larger valu…
Simulating pasta phases by molecular dynamics and cold atoms --- Formation in supernovae and superfluid neutrons in neutron stars
Gentaro Watanabe
In dense stars such as collapsing cores of supernovae and neutron stars, nuclear "pasta" such as rod-like and slab-like nuclei are speculated to exist. However, whether or not they…
Production of doubly strange hypernuclei via Ξ- doorways in the 16O(K-, K+) reaction at 1.8 GeV/c
Toru Harada, Yoshiharu Hirabayashi, Atsushi Umeya
We examine theoretically production of doubly strange hypernuclei, 16 Ξ-C and 16 ΛΛC, in doublecharge exchange 16O(K-, K+) reactions using a distorted-wave impulse approximation. T…
Single-pole nature of Lambda (1405) and structure of K-pp
Yoshinori Akaishi, Toshimitsu Yamazaki, Mitsuaki Obu +1
We have studied the structure of K- pp by solving this system in a variational treatment, starting from ansatz that Lambda(1405) is a K-p quasi-bound state, Lambda* with mass 1405…
