Excited states in As-82 studied in the decay of Ge-82

The excited states of odd-odd As-82 are studied in the beta decay of Ge-82. An isotopically pure beam of Ga-83 was produced at the Holifield Radioactive Ion Beam Facility using a resonance ionization laser ion source and high-resolution electromagnetic separation. The atoms of Ge-82 are created after beta-delayed neutron emission in the decay of Ga-83. The number of Ge-82 atoms is found by normalization to the 1348-keV gamma ray. Detailed analysis of the decay scheme is compared with shell-model calculations with several commonly used fpg shell interactions.
