S β( E) in Halo Nuclei]]>

摘要

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 M 1 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 S ~(β)( E ) of halo nuclei, may have np tango halo structure or mixed np tango + nn Borromean halo structure. Correct interpretation of halo structure is important in experiments on β-decay study, interpretation of M 1 γ-decay of IAR, and charge-exchange nuclear reactions analysis.
