    "abstract": "Four-body distorted wave theory appropriate for nucleon-nucleus reactions\nleading to 3-body continuum excitations of two-neutron Borromean halo nuclei is\ndeveloped. The peculiarities of the halo bound state and 3-body continuum are\nfully taken into account by using the method of hyperspherical harmonics. The\nprocedure is applied for A=6 test-bench nuclei; thus we report detailed studies\nof inclusive cross sections for inelastic $^6$He(p,p\u0027)$^6$He$^*$ and\ncharge-exchange $^6$Li(n,p)$^6$He$^*$ reactions at nucleon energy 50 MeV. The\ntheoretical low-energy spectra exhibit two resonance-like structures. The first\n(narrow) is the excitation of the well-known $2^+$ three-body resonance. The\nsecond (broad) bump is a composition of overlapping soft modes of\nmultipolarities $1^-, 2^+, 1^+, 0^+$ whose relative weights depend on\ntransferred momentum and reaction type. Inelastic scattering is the most\nselective tool for studying the soft dipole excitation mode.",
