Separability of a Low-Momentum Effective Nucleon-Nucleon Potential
H. Kamada, S. Fujii, E. Uzu +3
A realistic nucleon-nucleon potential is transformed into a low-momentum effective one (LMNN) using the Okubo theory. The separable potentials are converted from the LMNN with a un…
A new screening function for Coulomb renormalization
M. Yamaguchi, H. Kamada, Y. Koike
We introduce a new screening function which is useful for the few-body Coulomb scattering problem in ``screening and renormalization'' scheme. The new renormalization phase factor…
Complex Energy Method in 4-Body Faddeev-Yakubovsky Equations
E. Uzu, H. Kamada, Y. Koike
The Complex Energy Method [Prog. Theor. Phys. {\bf 109}, 869L (2003)] is applied to the 4-body Faddeev-Yakubovsky equations in the 4-nucleon system. We obtain a well converged solu…
Complex Energy Method for Scattering Processes
H. Kamada, Y. Koike, W. Gloeckle
A method for solving few-body scattering equations is proposed and examined. The solution of the scattering equations at complex energies is analytically continued to get scatterin…
9Be: A gateway nucleus into heavier nuclei?
Y. Koike
Level structure of 9Be is investigated calculating poles of the alpha alphar n three-body scattering amplitude in the complex energy plane. We find 10 levels, which make rotational…
