Study of various few-body systems using Gaussian expansion method (GEM)
Emiko Hiyama, Masayasu Kamimura
We review our calculation method, Gaussian expansion method (GEM), and its applications to various few-body (3- to 5-body) systems such as 1) few-nucleon systems, 2) few-body struc…
On the possibility of generating a 4-neutron resonance with a {\boldmath } isospin 3-neutron force
E. Hiyama, R. Lazauskas, J. Carbonell +1
We consider the theoretical possibility to generate a narrow resonance in the four neutron system as suggested by a recent experimental result. To that end, a phenomenological $T=3…
Resonant states of neutron-rich hypernucleus He
E. Hiyama, M. Isaka, M. Kamimura +2
The structure of neutron-rich hypernucleus, He is studied within the framework of an four-body cluster model. We predict second and states, corr…
Four-body structure of neutron-rich hypernucleus H
E. Hiyama, S. Ohnishi, M. Kamimura +1
The structure of heavy hyperhydrogen H is studied within the framework of a four-body cluster model. Interactions among the constituent subunits are determined so as t…
Complex-Scaling Calculation of Three-Body Resonances Using Complex-Range Gaussian Basis Functions --- Application to 3 resonances in 12C ---
Shin-Ichi Ohtsubo, Yoshihiro Fukushima, Masayasu Kamimura +1
We propose to use the complex-range Gaussian basis functions, {r^l e^{-(1 \pm iω)(r/r_n)^2}Y_{lm}(\hat{r}); r_n in a geometric progression}, in the calculation of three-body resona…
Linear correlations between 4He trimer and tetramer energies calculated with various realistic 4He potentials
E. Hiyama, M. Kamimura
In a previous work [Phys. Rev. A 85, 022502 (2012)] we calculated, with the use of our Gaussian expansion method for few-body systems, the energy levels and spatial structure of th…
