The level structure of {sup 219}Rn has been studied using the alpha decay of {sup 223}Ra and coincident gamma rays. While only modest changes are required in the level structure, and only above 342.8 keV, severe changes are required throughout the level scheme in the spin assigments. These changes allow the assignment of two sets of anomalous bands with K=5/2{sup {plus_minus}} and K=3/2{sup {plus_minus}}. The K=5/2{sup {plus_minus}} bands have configurations intermediate between the reflection asymmetric configuration and the g{sub 9/2} shell model configuration, while the K=3/2{sup {plus_minus}} bands have configurations intermediate between the mixed reflection asymmetric configuration and the i{sub 11/2} shell model configuration. Comparison of the systematics of {sup 219}Rn with neighboring isotones, isobars, and isotopes shows clearly the collapse of the quadrupole-octupole-type configurations into the less degenerate shell model configurations. {copyright} {ital 1998} {ital The American Physical Society}
