Abstract
The proton decay of the highly deformed odd-odd nucleus has been observed by bombarding a target with a beam of ions. Fusion evaporation residues were separated in-flight using the Argonne fragment mass analyzer and implanted into a double-sided silicon strip detector. decays by the emission of a proton with energy and half-life . The transition is assigned to a highly deformed ground-state configuration by comparing the decay rate with a new theoretical formalism for deformed odd-odd nuclei. These results clearly demonstrate the sensitivity of the proton decay rate to the spectator neutron configuration.
