Quenching of Axial-Vector Weak Interaction Constant in Halo Nuclei
Resonance structure of the beta decay strength function S β ( E ) for GT β – -decay of halo nuclei 6 He and 11 Li is analyzed. Compare experimental total strength for β-transitions in units with the Ikeda sum rule (in units) one can determine the squared ratio of axial-vector and vector weak interac...
