Rotational dependence of Coulomb energy differences

The rotational dependence of Coulomb energy differences is investigated throughout the f7/2 shell using a cranked shell model framework. Predictions are made for the change in Coulomb energy differences at the first band crossing of odd- and even-mass mirror nuclei. It is found that this change is smaller in even-mass mirror nuclei where it depends critically on the relative shift in the bandcrossing frequencies of the two mirror nuclei. These results account for the recently observed behaviour in the A=47 and 49 mirror nuclei.
