摘要
We study the dependence of the total Gamow-Teller strength in an N=Z nucleus (Mg-24) as a function of excitation energy within a complete O (h) over bar omega shell-model space (the Od1s shell). We find an essentially monotonic increase in strength with increasing excitation energy. We are able to relate this behavior to a decrease in spatial symmetry (increase in SU(4) symmetry) as a function of excitation energy. (C) 1997 Elsevier Science B.V.
