Isospin identification for highly-excited Gamow—Teller and M1 states in mirror nuclei

Under the assumption that nuclear interaction is charge symmetry, isospin T is a good quantum number. Exotic nuclei have large |T z | values, where T z is defined by (N — Z)/2. Assuming isospin is a good quantum number, the analog states of the low-lying states in the T z = ±(T 0+ 1) nuclei can be found as the highly excited T 0+ 1 states in T z = ±T 0 nuclei. Therefore, if T 0 + 1 states are identified in highly excited region of T z = ±T 0 nuclei, the structure of the exotic nuclei with T z = ±(T 0 + 1) can be deduced.
