Abstract
We investigate the spin-flip charge-exchange type nuclear excitations, that are, Gamow-Teller (GT) and isovector-spin-monopole (IVSM) transitions, to explore a possible probe to study the two-neutron correlations in the halo nuclei. A typical light halo nucleus, \(^6\)He, is studied with \(^4\)He (\(\alpha \)) \(+\) two-nucleon (N) three-body model. We show that the IVSM transitions are superior to the GT ones to obtain the information on the structure of \(^{6}\)He: The strong IVSM strengths, which are sensitive to the binding energy of \(^6\)He, are found in the low-lying region below the \(\alpha +\)deuteron (d) threshold, whereas the GT strengths have almost no peak due to small overlap between the wave functions of the ground state of \(^6\)He and the \(\alpha +d\) continuum of \(^6\)Li.
