Abstract
It is shown that when the parent nucleus has nn Borromean halo structure, then after Gamow-Teller (GT) β -decay of parent state or after M1 γ -decay of Isobar Analogue Resonance ( IAR ) the states with np tango halo structure or mixed np tango + nn Borromean halo structure can be populated. Resonances in the GT β -decay strength function Sβ (E) of halo nuclei may have np tango halo structure or mixed np tango + nn Borromean halo structure. Demonstrated that the nuclei with Z/N ≈ 0.6 may correspond to the SU(4) region.
