ABSTRACT

It is shown that when the parent nucleus has nn Borromean halo structure, then after Gamow-Teller (GT)  ß-decay of parent state or after M1 gamma-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 ß-decay strength function Sß(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.


KEYWORDS

borromean halo, tango halo, mixed halo, beta decay strength function, SU(4) symmetry, SU(4) region.
