Rotational bands and alignments in the 1f 7/2 shell

Nuclei in the middle of the If 7/2 shell are shown to have rotational features. Dynamic electromagnetic moments have been measured for many transitions. The agreements of large-scale shell model calculations with experimental data is in general excellent. A K-value was assigned to various bands, which can be described in the strong-coupling approximation. Evidence of band crossings is giver The proposed description agrees with observed Coulomb energy differences.
