摘要：
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, He-6, is studied with He-4 (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 He-6: The strong IVSM strengths, which are sensitive to the binding energy of He-6, 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 He-6 and the alpha + d continuum of Li-6.
