Abstract
We report on the first successful extraction of a Gamow-Teller strength distribution from a radioactive isotope in an intermediate-energy charge-exchange experiment in inverse kinematics. The () reaction at was used to measure Gamow-Teller transition strengths from to states in . The results show that little mixing occurs between and shell configurations for the low-lying and states even though neighbors the island of inversion and low-lying intruder states exist. Shell-model calculations in the model space are consistent with these findings.
