Abstract
Proton radioactivity from and has been identified. The proton transition has an energy , a half-life , and is assigned to the decay of the Nilsson state. The transition has an energy and a half-life of 26(6) ms, consistent with decay from either the or Nilsson orbital. The proton decay rates deviate significantly from calculations assuming spherical configurations, and thus indicate the onset of large deformations in the region of the proton drip line below .
