New aspects of structure which stem from the interplay of isospin and collectivity are discussed. New results on Coulomb energy differences (CED) at high spin in the f[sub 7/2] shell are interpreted in the framework of a simple Cranked Shell Model treatment involving an exact numerical diagonalization. Predictions are shown for CED between even-even mirror pairs as a function of rotational frequency. Signatures of neutron-proton pairing are discussed and the CED between the T=1 states in N=Z odd-odd nuclei and their isobaric analogues are suggested as a possible probe of n-p pairing on the N=Z line. © 2000 American Institute of Physics.
