The excited states of odd-odd As82 are studied in the β decay of Ge82. An isotopically pure beam of Ga83 was produced at the Holifield Radioactive Ion Beam Facility using a resonance ionization laser ion source and high-resolution electromagnetic separation. The atoms of Ge82 are created after β-delayed neutron emission in the decay of Ga83. The number of Ge82 atoms is found by normalization to the 1348-keV γ ray. Detailed analysis of the decay scheme is compared with shell-model calculations with several commonly used fpg shell interactions.
