Four-body resonances of 7B using the complex scaling method
Takayuki Myo, Yuma Kikuchi, Kiyoshi Kato
We study the resonance spectroscopy of the proton-rich nucleus 7B in the 4He+p+p+p cluster model. Many-body resonances are treated on the correct boundary condition as the Gamow st…
Isoscalar monopole excitations in O: -cluster states at low energy and mean-field-type states at higher energy
T. Yamada, Y. Funaki, T. Myo +5
Isoscalar monopole strength function in O up to MeV is discussed. We found that the fine structures at the low energy region up to MeV in t…
Role of the tensor interaction in He isotopes with a tensor-optimized shell model
Takayuki Myo, Atsushi Umeya, Hiroshi Toki +1
We studied the role of the tensor interaction in He isotopes systematically on the basis of the tensor-optimized shell model (TOSM). We use a bare nucleon-nucleon interaction AV8 o…
Constraint Propagation of -adjusted Formulation II --- Another Recipe for Robust Baumgarte-Shapiro-Shibata-Nakamura Evolution System ---
Takuya Tsuchiya, Gen Yoneda, Hisa-aki Shinkai
In order to obtain an evolution system which is robust against the violation of constraints, we present a new set of evolution systems based on the so-called Baumgarte-Shapiro-Shib…
Neutrino Mass Matrix with No Adjustable Parameters
Yoshio Koide, Hiroyuki Nishiura
On the basis of the so-called "yukawaon" model, we found out a special form of the neutrino mass matrix which gives reasonable predictions. The is given by a multiplica…
Tensor-optimized few-body model for s-shell nuclei
Kaori Horii, Hiroshi Toki, Takayuki Myo +1
As a new scheme of treating the tensor interaction of the nucleon-nucleon interaction, there is a proposal of a tensor-optimized shell-model (TOSM) for the study of medium and heav…
