The He3(He4,gamma)Be7 and H3(He4,gamma)Li7 reactions are studied in an extended two-cluster model which contains alpha+h/t and Li6+p/n clusterizations. We show that the inclusion of the Li6+p/n channels can significantly change the…

Variational calculations for s-shell hypernuclei are performed by explicitly including $\Sigma$ degrees of freedom. Four sets of YN interactions (SC97d(S), SC97e(S), SC97f(S) and SC89(S)) are used. The bound-state solution of $_\Lambda^5$He…
Background: The four-neutron correlation has been attracting much attention for decades. In addition to the study on the tetra-neutron system, it is worthwhile to investigate the correlation in bound systems. Purpose: The $^8$He nucleus is…
