Beta-delayed proton emission was observed for the N=83 precursor153Yb. This extends the region of delayed proton emission in the lanthanides across the N=82 shell for the first time. The 4.0±0.5 s delayed proton activity was assigned to153Yb on the basis of mass separation, coincident Tm K x rays, and coincident γ-ray transitions in the daughter nucleus152Er. Proton final state branching ratios are consistent with a 7/2- precursor spin. The proton branching ratio is (8±2)×l0-5.
