Electroexcitation of 8/sup -/ states in /sup 52/Cr

Inelastic electron scattering at incident energies between 170 and 260 MeV was used to identify and study M8 transitions in /sup 52/Cr. A strong transition to an 8/sup -/ state at E/sub x/ = 15.47 MeV was observed, as well as a number of weaker transitions. The results are compared with a single particle-hole shell model calculation that uses a model space of the form ((f/sub 7/2//sup 11/ x g/sub 9/2/)/sub 8//sub -/. The shell model calculation and systematics in neighboring nuclei were used to determine the isospin of the observed states. The experimentally determined strengths exhaust 60.8% and 34.5% of the T = 3 and T = 2 sum rules, respectively.
