Possible lightest Hypernucleus with Modern Interactions
E. Hiyama, K. Sasaki, T. Miyamoto +4
Experimental evidence exists that the -nucleus interaction is attractive. We search for and bound systems on the basis of the AV8 potential combined with eithe…
Equation of state for neutron stars with hyperons by the variational method
H. Togashi, E. Hiyama, Y. Yamamoto +1
We investigate the effects of the odd-state part of bare interactions on the structure of neutron stars (NSs) by constructing equations of state (EOSs) for uniform nuclear mat…
Hyperon-mixed neutron star with universal many-body repulsion
Y. Yamamoto, T. Furumoto, N. Yasutake +1
Neutron stars with large masses require the hard stiffness of equation of state (EoS) of neutron-star matter. On the other hand, hyperon mixing brings about remar…
Hyperon mixing and universal many-body repulsion in neutron stars
Y. Yamamoto, T. Furumoto, N. Yasutake +1
A multi-pomeron exchange potential (MPP) is proposed as a model for the universal many-body repulsion in baryonic systems on the basis of the Extended Soft Core (ESC) bryon-baryon…
Analyzing power in elastic scattering of 6He from polarized proton target at 71 MeV/nucleon
S. Sakaguchi, Y. Iseri, T. Uesaka +33
The vector analyzing power has been measured for the elastic scattering of neutron-rich 6He from polarized protons at 71 MeV/nucleon making use of a newly constructed solid polariz…
Five-body cluster structure of double- hypernucleus Be
E. Hiyama, M. Kamimura, Y. Yamamoto +1
Energy levels of the double hypernucleus, Be are calculated within the framework of an five-body model. Interactions between constituent particles are dete…
Structure of A=7 iso-triplet hypernuclei studied with he four-body model
E. Hiyama, Y. Yamamoto, T. Motoba +1
The structure of the T=1 iso-triplet hypernuclei, He, Li and Be within the framework of an four-body cluster model is studied. Interactions between the…
Four-body structure of Li and spin-dependent interaction
E. Hiyama, Y. Yamamoto, Th. A. Rijken +1
Two spin-doublet states of %- and - in Li are studied on the basis of the four-body model. We employ the two-body interactions which rep…
Soft-core hyperon-nucleon potentials
Th. A. Rijken, V. G. J. Stoks, Y. Yamamoto
A new Nijmegen soft-core OBE potential model is presented for the low-energy YN interactions. Besides the results for the fit to the scattering data, which largely defines the mode…
