    "abstract": "The neutron halo structure of $^{6}$He and of $^{8}$He is studied in a\nmicroscopic three-body and five-body model, respectively. Various cluster\narrangements are included to embody a variety of correlations between the\nclusters. The intercluster wave function is determined with the stochastic\nvariational method. The $^{6}$He and $^{8}$He energies are reproduced with the\nsame effective force very well. The radii and densities are compared with the\nresults of empirical analyses. The calculated difference of the neutron and\nproton radii exceeds 0.8 fm, confirming the thick neutron skin. The two-neutron\nremoval spectroscopic amplitudes are calculated and used for evaluating the\nmomentum distribution and the $\\beta$ decay spectrum, which are sensitive to\nthe halo structure. A fair agreement with experiment is obtained.",
