摘要：
The strength distributions of Gamow-Teller (GT) transitions from Li-11 and Be-12 are investigated. We study where the GT strengths of the transitions Li-11 (3/2 (g) over bar.s.) --> Be-11* (1/2(-), 3/2(-), 5/2(-)) are located incorporating quenching effects due to the Delta-hole contributions. The connection between the GT sum rule and effects of the halo structure of Li-11 are discussed. The narrowing of the gap between the p-shell and the sd-shell is found to change the structure of the GT strength distribution.
