摘要：

The parameters which determine the decay characteristics of mixed-symmetry states are evaluated for a wide range of N and Z. Effective charges, e pienu, are obtained from B(E2;21 +-O1+) values for chains of isotopes and isotones, g pi g nu values are calculated from the magnetic moments of 2 1+ states and the behaviour of chi pi chi nu is considered. Regions are identified where these parameters favour strong signatures for the lowest lying 2+ mixed-symmetry states in vibrational-like nuclei. The influence of the parameters on B(M1) and B(E2) values in rotational nuclei is considered.
